International product information lists 3JALBI as a Korean-origin brand manufactured by CureLife.3

3JALBI emerged from CureLife, a South Korean manufacturer founded in 2018. Early corporate materials identified the 3JALBI broom as the company’s principal product and described CureLife as a manufacturer focused on integrating consumer needs into its designs.3

Rather than treating the broom as a basic commodity, the company prioritized product development and engineering. According to CureLife’s trade profile, 3JALBI products were developed with specific attention to usability and design details to enhance consumer convenience. The company also utilized crowdfunding as part of its launch strategy, stating that approximately 10,000 people participated in the manufacturing of the original 3JALBI by 2019.4

This consumer-oriented development model became central to the brand’s identity, distinguishing it from conventional cleaning tools by redesigning the basic broom around actual household cleaning behaviors.

The defining concept behind 3JALBI is the replacement or supplementation of conventional broom bristles with a flexible rubber-blade cleaning surface. This design allows a single tool to perform functions typically associated with multiple cleaning implements.

For example, the J01 model combines broom, scraper, and wiper functions. Its construction uses PP, elastomer/TPE, and aluminum, with an overall length of 950 mm and a weight of approximately 230 g.5 The later J02 model offers similar multifunctionality with an adjustable shaft ranging from approximately 900 to 1,400 mm depending on configuration.5

The 3JALBI Super Broom is the product most closely associated with the brand. Unlike traditional brooms that primarily gather loose dry debris, the 3JALBI design utilizes a flexible rubber-like blade system capable of interacting with various materials and surfaces.

The manufacturer promotes the Super Broom for tasks including:

• Dust and debris collection
• Hair and pet fur removal
• Water removal
• Bathroom and toilet-area cleaning
• Window cleaning
• Collection of broken or coarse debris
• General household sweeping

The product is described as capable of cleaning “every nook and cranny,” emphasizing its versatility across different household environments.7

A distinctive aspect of 3JALBI is its emphasis on patented structural design. The original product concept is built upon a four-layer rubber blade. BRAINCENSE describes 3JALBI as having begun with an in-house-developed patented four-layer rubber-blade broom.6

This design is intended to provide:

• Flexibility
• Firm surface contact
• Debris collection
• Water removal
• Scraping capability
• Reduced dust disturbance
• Durability

Patent documentation describes a frame incorporating multiple air paths to reduce airborne dust during sweeping, alongside flexible yet rigid structural components in the broom head.7 This reflects the brand’s philosophy of solving functional shortcomings through engineering rather than aesthetic changes.

Intellectual property development is integral to the 3JALBI brand. International product documentation cites Korean patent 10-1432074, dated August 13, 2014, alongside later filings such as PCT-KR190522-006154.6 Additional Korean patent 10-2150876, dated August 27, 2020, is also listed.8

A profile by Small Brander reported that 3JALBI held three Korean patents and had 21 overseas patents either registered or applied for at the time of publication. The same source noted that the brand built significant sales around a small number of broom products rather than a large catalog.7 Historically, 3JALBI’s differentiation has been based on functional innovation rather than product variety.

While the Super Broom is the flagship item, 3JALBI has developed a family of related products:

3JALBI J01

The earlier full-size broom design combining sweeping, scraping, and wiping functions.9

3JALBI J02

A later full-size extendable version featuring an adjustable shaft and similar multifunctional cleaning capabilities.5

HANDI JALBI

A smaller handheld version designed for localized cleaning tasks.9

MINI JALBI

A compact version intended for smaller spaces and quick cleaning.10

Accessories

The ecosystem includes dustpans, collection systems, and replacement heads. Retail listings offer various combinations of 3JALBI, Handi Jalbi, and Mini Jalbi units alongside spare parts.10

3JALBI’s philosophy centers on three core principles:

Practicality

The brand aims to make cleaning tools do more with fewer components. A single 3JALBI unit can function as a broom, scraper, and wiper, eliminating the need for separate tools.11

Consumer-centered development

CureLife describes consumer feedback and communication as fundamental to its process. Products are designed around consumer convenience, addressing both broad usability and specific details.12

Engineering-led design

Instead of competing primarily through decoration or branding, 3JALBI emphasizes patents, materials, construction, and functional performance. This approach distinguishes the brand from conventional household brooms.

3JALBI exemplifies a small-category consumer brand that initially concentrated on a single product category rather than expanding into unrelated household goods. A 2022 Small Brander profile reported that the brand was approaching KRW 5 billion in annual sales while focusing essentially on the broom category. Overseas markets reportedly accounted for nearly 40% of sales in 2022.12

These figures are derived from a third-party brand interview rather than audited financial statements and should be regarded as reported data. Nevertheless, they illustrate the brand’s growth strategy of building a recognizable consumer identity around a common household tool.

3JALBI has pursued markets outside South Korea, maintaining English-language product and corporate materials. The international site identifies the manufacturing base in Siheung, Gyeonggi Province, South Korea, and presents the product as a Korean-developed cleaning tool.13

The brand appears on international B2B platforms and distributor sites, where products are listed as Korean-origin goods manufactured by CureLife.13 Evidence of U.S. distribution or licensing relationships further indicates commercial activity beyond Korea.13

In 2025, CureLife introduced BRAINCENSE as a new overarching brand identity. The company explicitly describes BRAINCENSE as “the new name for 3Jalbi,” explaining the move as a shift beyond cleaning tools into broader hygiene, convenience, and lifestyle areas.14

Under the current brand architecture:

• BRAINCENSE: Umbrella brand
• 3JALBI: Hero cleaning brand

BRAINCENSE refers to 3JALBI as its “hero brand.”21 Consequently, 3JALBI is now accurately described as the flagship clean-care brand within the BRAINCENSE ecosystem rather than the entirety of the company’s operations.

Origin of the name BRAINCENSE

The name BRAINCENSE combines “brain” and “incense.” According to the company, this represents ideas coming together to create products whose influence spreads quietly like a subtle fragrance. The “cense” portion also evokes “sense,” representing intuition and perception.22

This change reflects a strategic evolution:

• 3JALBI: Cleaning → broom innovation → clean-care products
• BRAINCENSE: Ideas + manufacturing expertise → hygiene + convenience + lifestyle

3JALBI served as the proof of concept for the company’s development philosophy, which BRAINCENSE now applies to a wider range of everyday products.

3JALBI’s identity is built on the contrast between an ordinary product category—the broom—and a deliberately technical approach. Rather than presenting cleaning as a mundane chore, the brand treats the tool as a piece of industrial and product design, emphasizing function, materials, patents, ergonomics, convenience, and design. This technical focus has enabled 3JALBI to build a recognizable brand around a commodity product.

From a brand-analysis perspective, 3JALBI’s strengths include:

• Strong product differentiation: Rubber-blade construction provides immediate functional distinction from conventional bristle brooms.
• Clear hero product: The Super Broom anchors the brand’s identity.
• Intellectual-property protection: Patents and technical development create barriers to imitation beyond aesthetic branding.7
• Multifunctionality: Sweeping, scraping, and wiping capabilities position the product as a versatile tool.15
• Korean manufacturing identity: The brand leverages Korean manufacturing and development expertise in its positioning.16
• International potential: English-language materials and overseas distribution demonstrate global applicability.17

Specialization presents potential limitations. For years, the brand was heavily associated with a single product category, creating a strong identity but potentially restricting long-term growth without extension into other categories.

The development of BRAINCENSE addresses this challenge. By preserving 3JALBI’s identity as a cleaning specialist while using BRAINCENSE as a broader platform, CureLife can expand its portfolio without diluting the core brand’s equity.18

3JALBI demonstrates how product innovation can transform a low-interest commodity into a branded consumer product. The brand improved fundamental aspects of the broom, including debris collection, water removal, dust disturbance, handling comfort, multitasking capability, and storage.

Its trajectory aligns with a broader trend in Korean consumer products where smaller manufacturers utilize engineering, patents, crowdfunding, and direct consumer feedback to compete against established household goods companies.

As of 2026, 3JALBI is a South Korean clean-care brand created by CureLife, best known for patented rubber-blade multifunctional brooms. Following the introduction of BRAINCENSE, 3JALBI is positioned as the flagship cleaning brand within the ecosystem, while BRAINCENSE represents the company’s broader expansion into hygiene, convenience, and lifestyle products.19

The official 3JALBI site continues to list products such as the J01/J02, Handi Jalbi, and Mini Jalbi, while the BRAINCENSE site presents 3JALBI within its family-brand structure.20
