Foundation

Pao Shen Enterprises was established in 1976 in Changhua, Taiwan. The company’s founder and chairman, Jackson Huang, built the business around manufacturing stationery and office products, with an emphasis on product quality and industrial production capabilities. The Taiwan Association of Stationery Industries lists the company’s establishment date as 24 May 1976 and identifies Kw-Trio as its brand.

From its Taiwanese manufacturing base, Pao Shen gradually developed Kw-Trio as an export-oriented brand. Rather than concentrating on only one category of stationery, the company expanded into a broad range of desktop tools and paper-handling equipment.

Development of the brand

Kw-Trio’s corporate philosophy is summarised by three concepts: “Progress, Harmony and Innovation.” The company describes these ideas as central to its development and product philosophy.[1]

The company has also explained the name Kw-Trio through several brand concepts. Taiwan Excellence materials state that “K” represents “kinds” and “W” represents “the world,” while “Trio” is associated with harmony, progress, and innovation. Another Taiwan Excellence listing offers a different historical explanation, associating KW with the former Kaiwei steel works. Because published materials are not entirely consistent regarding the exact etymology, the most accurate description is that “Trio” is explicitly connected with the brand’s three philosophical values, while the precise origin of “KW” has been described in more than one way.

International expansion

Kw-Trio subsequently developed a substantial international export business. The company states its products reach over 110 countries, making international distribution a key part of the brand’s identity. It has also undertaken OEM/ODM manufacturing alongside its own Kw-Trio branded products.

The company’s presence at international trade exhibitions—including Paperworld/AMBIENTE, drupa, Canton Fair, International Hardware Fair Cologne, National Hardware Show, and other industry events—reflects its positioning as an international B2B manufacturer rather than solely a consumer stationery label.[1]

Kw-Trio maintains one of the broader product portfolios among specialist stationery manufacturers. Its current catalogue is divided into several major areas.[1]

Staplers

Staplers are arguably Kw-Trio’s signature product category. The company produces:

• Standard desktop staplers
• Full-strip and half-strip staplers
• Heavy-duty staplers
• Long-reach staplers
• Electric staplers
• Flat-clinch staplers
• Effortless/ergonomic staplers
• Pocket staplers
• Stapleless staplers
• Specialty staplers
• Staples and staple removers

Kw-Trio describes the stapler as one of its most important product lines and emphasises its extensive range, including models designed for heavy-duty work, long-reach applications, temporary stapling, flat stapling, and staple-free operation.[1]

Its electric staplers are particularly engineering-oriented. The company states that some heavy-duty electric models can staple up to 80 sheets of 64-gsm paper, while flat-clinch designs are intended to produce a flatter finished stack.[1]

Paper punches

Another major Kw-Trio category is the paper punch. The range includes:

• Standard manual punches
• Heavy-duty punches
• Effortless punches
• Electric punches
• Multi-hole punches
• Replacement cutter sets
• Specialty punches

The brand has emphasised reducing the physical force required to operate punches. One of its “Eternity Easy-Tech” punches, for example, was promoted as requiring roughly 50% less operating power than a conventional punch.

Paper cutters and trimmers

Kw-Trio has a significant presence in paper-cutting equipment, including:[1]

• Paper guillotines
• Heavy-duty guillotines
• Rotary paper trimmers
• Lightweight paper trimmers
• Specialty cutting tools
• Cutting mats
• Replacement blades

This category supports the company’s professional-office positioning, as these products serve printing, education, graphic production, administrative, and general document-processing applications.[1]

Manual tackers and hand tools

Kw-Trio also produces manual tackers and related hand tools. Its tacker range is designed for applications such as:

• Packaging
• Upholstery
• Display work
• Crafting
• Floristry
• Light construction
• General DIY work

One of the company’s best-known innovations is its Easy-Tech Tacker, designed to reduce the squeezing force required from the user. Taiwan Excellence materials describe the design as an ergonomic, effort-saving mechanism, with certain models requiring substantially less force than conventional tackers.

The company also produces riveters and nail dispensers within its hand-tool portfolio.[1]

Traditional stationery

Kw-Trio’s stationery portfolio includes many smaller desktop products, such as:

• Pencil sharpeners
• Automatic numbering machines
• Stamps
• Tally counters
• Call bells
• Tape dispensers
• Business-card cases
• Bookends
• Scissors
• Cutting knives
• Corner rounders
• Stationery accessories
• Stationery gift sets

The breadth of this range demonstrates that Kw-Trio is not solely a stapler manufacturer; it aims to provide a complete set of document-handling and desktop tools.[1]

TO NOTE

TO NOTE is a Kw-Trio product line focused on modular notebooks and related accessories. The system includes:

• Reconfigurable notebooks
• Punches
• Page refills
• Accessories
• Ruler/fixture components
• Gift sets

The concept allows users to add, remove, and rearrange pages rather than treating a notebook as a permanently bound object.[1]

Office furniture and SOHO products

Kw-Trio has expanded beyond traditional stationery into office and home-office products. Its catalogue includes:

• Ergonomic office chairs
• Executive chairs
• Visitor chairs
• School chairs
• Mesh chairs
• Chair mechanisms and components
• Height-adjustable standing desks
• Selected safe/deposit-box products

The company’s current catalogue therefore spans everything from small staplers to larger workplace equipment.[1]

A defining characteristic of Kw-Trio is that it presents itself primarily as a manufacturer, rather than simply a stationery brand that outsources production.

Pao Shen states it has invested in advanced manufacturing and tooling facilities and maintains its own R&D capabilities. Taiwan Excellence materials have described the company as having more than 100 R&D/technical staff and facilities supporting its own-brand and OEM/ODM production.

The company has also emphasised vertical integration, precision machinery, tooling, and product development. This is particularly relevant for products such as metal staplers, punches, tackers, and paper cutters, where mechanical engineering and tooling directly affect durability and performance.[1]

Quality control has been a recurring part of Pao Shen’s corporate positioning.

According to company and Taiwan Excellence materials, Pao Shen began implementing the ISO 9001 international quality-management system in the 1990s and obtained ISO 9001 certification. More recent company materials state that it maintains ISO 9001:2015 and ISO 14001:2015 certifications, with the latter relating to environmental management.

This is consistent with Kw-Trio’s positioning as an industrial manufacturer serving international markets rather than as a purely low-cost stationery brand.

Kw-Trio/Pao Shen has received recognition through the Taiwan Excellence programme, which evaluates Taiwanese products using criteria including R&D, design, quality, and marketing.

The company’s award-related products have included:

• Staplers
• Tackers
• Punches
• Electronic staplers
• Paper trimmers
• Notebooks

Taiwan Excellence records specifically identify several Kw-Trio/Pao Shen products as award winners, including ergonomic stapling and punching products.

This recognition is significant because it reinforces Kw-Trio’s attempt to differentiate itself through engineering and product innovation, rather than competing solely on price.

Kw-Trio’s philosophy can broadly be understood through three words:

Progress

The company emphasises continuous product development and improvement. This is visible in its evolution from conventional metal stationery towards ergonomic staplers, electric products, sophisticated paper cutters, and other specialised tools.

Harmony

“Harmony” is used not merely as a corporate value but as part of the brand’s conceptual identity. The company describes its products as tools intended to integrate work, learning, and everyday life.

Innovation

Innovation is perhaps the most visible of the three values in Kw-Trio’s product strategy. Examples include effort-saving staplers and punches, flat-clinch mechanisms, stapleless staplers, multi-purpose tackers, and modular notebook systems.

Kw-Trio products generally combine mechanical functionality with user-oriented design.

A recurring theme is reducing the amount of effort required from the user. This can be seen in:

• Effortless staplers
• Effortless punches
• Electric staplers
• Easy-Tech tackers
• Lightweight trimmers
• Flat-clinch staplers
• Specialty multi-function tools

The company therefore occupies an interesting position between conventional stationery and small-scale industrial equipment: its products may look like ordinary office tools, but many are designed around mechanical engineering and ergonomic performance.[1]

Kw-Trio can best be described as a Taiwanese professional stationery and office-tool manufacturer with a strong engineering orientation.

Its market positioning differs somewhat from mass-market stationery companies:

Traditional stationery brands often compete through low prices, colourful consumer products, and broad retail distribution.

Kw-Trio, by contrast, has historically emphasised:

• Manufacturing expertise
• Metal construction
• Mechanical durability
• Ergonomics
• Professional applications
• Product innovation
• Paper-processing equipment
• B2B/export markets
• OEM/ODM manufacturing

Its catalogue consequently includes products aimed at ordinary office users as well as schools, print-related businesses, professional workplaces, retail environments, workshops, and DIY users.

The company states that Kw-Trio products are exported to more than 110 countries. Its participation in international trade fairs further demonstrates the importance of overseas distribution to the business.

The brand’s international identity is therefore closely tied to Taiwan’s manufacturing sector: products are developed and manufactured in Taiwan while being marketed to customers and distributors around the world.

As of 2026, Pao Shen Enterprises continues to operate from its facility in Dacun Township, Changhua County, Taiwan. The company’s official website lists the address as 162-1 Shen Chiao Road, Da-Tsun Hsiang, Changhua, Taiwan 51541.[1]

The company remains active in international exhibitions. Its current news listings include participation in the 2026 National Hardware Show, 2026 International Hardware Fair Cologne, 2026 AMBIENTE, and the 139th Spring Canton Fair, indicating continuing international business activity.[1]

One point that can easily cause confusion is the distinction between Kw-Trio and Pao Shen Enterprises.

• Pao Shen Enterprises Co., Ltd. is the company/manufacturer.
• Kw-Trio is its principal consumer-facing/professional brand.
• Pao Shen manufactures products under the Kw-Trio name.
• Pao Shen also undertakes OEM/ODM projects in addition to its own-brand business.

In other words, it is more accurate to describe Kw-Trio as a brand of Pao Shen Enterprises than to treat Kw-Trio and Pao Shen as two completely separate companies.

Several characteristics particularly define Kw-Trio:

1. Taiwanese manufacturing heritage — the business dates to 1976 and is based in Changhua.
2. Stapler expertise — staplers remain one of the company’s most prominent product categories.[1]
3. Mechanical engineering — many products emphasise mechanisms, metal construction, tooling, and durability.
4. Ergonomics — reducing operating force is a recurring theme in its punches, staplers, and tackers.
5. Broad product portfolio — the company covers stationery, paper cutters, hand tools, notebooks, and office furniture.[1]
6. International orientation — the company reports exports to more than 110 countries.
7. Own-brand and OEM/ODM capability — Pao Shen combines Kw-Trio-branded products with contract manufacturing.
8. Product awards and design recognition — several products have received Taiwan Excellence recognition.

Kw-Trio is particularly associated with staplers, hole punches, and paper cutters. Among stationery enthusiasts and professional users, the brand’s appeal tends to come from its combination of relatively conventional office tools with more sophisticated mechanical designs.

Its identity can therefore be summarised as “engineered stationery”: products that perform familiar office tasks but are differentiated through construction, mechanisms, ergonomics, and specialised functionality.

Kw-Trio is a Taiwanese stationery and office-tool brand founded around the manufacturing capabilities of Pao Shen Enterprises, a company established in 1976 by Jackson Huang. Starting from traditional stationery manufacturing, the company developed into an international producer of staplers, punches, paper trimmers, guillotines, tackers, and other desktop and workplace equipment.

The brand’s central philosophy—Progress, Harmony and Innovation—is reflected in its emphasis on product engineering, ergonomic design, and continuous development. Its international export network, OEM/ODM capabilities, ISO-certified quality-management systems, and Taiwan Excellence recognition have helped establish Kw-Trio as a notable Taiwanese manufacturer in the global stationery and office-equipment market.
