What Teibow does

Teibow Co., Ltd. is a Japanese B2B manufacturer of porous-material products, primarily pen nibs for writing instruments, where it holds the world's leading market share. Founded in 1896 in Hamamatsu as a hat manufacturer, the company pivoted in 1957 to pen nib manufacturing by leveraging its felt-processing expertise and has since built a roughly 5-billion-units-per-year, ~3,400-variety business spanning fiber, felt, plastic, sintered, PBT brush, and polyurethane porous nibs. The product portfolio has since expanded into cosmetic applicators (liquid eyeliners, mascara brushes, nail art, remover tips), stylus pen nibs for tablets, medical tubing, filtration products, and fragrance wicking components.

The company's products are built around capillary force control technology for porous materials, which engineers ink absorption, retention, and flow through fiber diameter/count and internal pore pattern design. Manufacturing and R&D are consolidated at the Miyakoda Technical Center, with a dedicated NEXT development facility accelerating design-to-production cycles and a patented hollow plastic ink feeder (JP 558718) enabling differentiated features such as enhanced glitter effects in brush pens. Approximately 350 customers in 45+ countries are served through direct B2B OEM/ODM engagements, with minimum orders around 100,000 units and sales-led motion via dedicated inquiry channels by application.

Teibow is a 100% subsidiary of Teibow Holdings Co., Ltd., which is itself wholly owned by TSE Prime-listed NORITSU KOKI Co., Ltd. The April 2025 spin-off of its Metal Injection Molding (MIM) business into Hamamatsu Metal Works Co., Ltd. recasts Teibow as a focused porous-material platform across writing, cosmetics, and emerging medical, industrial, and consumer applications. Wholly-owned subsidiaries include TEIBOW NIB MANUFACTURING (CHANG SHU) Co., Ltd. in China (est. 2012) and soliton Co., Ltd. in Nara (acquired 2019, brush manufacturing).

Core offering

Teibow manufactures and sells porous-material components, principally marker pen nibs and cosmetic applicators, using its proprietary capillary force control technology. It produces fiber, felt, plastic, sintered, PBT brush and rubber nibs for writing instrument and cosmetics brands, plus new-field porous products (medical tubes, filters, fragrance wicks, stylus nibs) and MIM metal parts.

Product overview

Teibow is a Japanese manufacturer of porous material products, primarily pen nibs (writing instrument tips) where it holds the world's top market share. The company operates across three main business segments: Writing Instruments (pen nibs including fiber, felt, plastic, PBT brush, sintered, and rubber nibs), Cosmetics (applicators for liquid liner, mascara, nail, and remover products), and New Fields (medical tubes, filters, air freshener components, and stylus pen nibs). A fourth segment, MIM (Metal Injection Molding), was spun off into Hamamatsu Metal Works in April 2025. All products leverage Teibow's core competency in capillary force control technology for porous materials, enabling precise management of liquid absorption, retention, and flow. The company offers approximately 3,400 product varieties and handles customization requests with minimum orders of 100,000 units.

Products and services

• Fiber Nib Porous fiber tips made from polyester, acrylic, or nylon fibers combined with resin, with approximately 3,000 combinations available. Diameter is customizable from φ1 to φ10, controlling capillary force for ink absorption, retention and flow. Sold to writing instrument manufacturers.
• Felt Nib Pen nibs produced by die-cutting plate-shaped felt material into 2D tip shapes, suited for large-sized nibs used in painting large areas, industrial applications, and high-durability requirements.
• Plastic Nib Extruded plastic tube nibs with internal pores that create capillary force, enabling ultra-fine diameters difficult to achieve with fiber tips. Over 50 internal pattern variations are available to customize writing feel and ink flow.
• PBT Brush Polybutylene terephthalate brush nibs developed using plastic extrusion technology. Softer than traditional fiber, with unique cross-sectional fiber shapes providing volume for mascara and artistic brush applications, available from φ1.2 to φ5.0.
• Sintered Nib Polyethylene sintering nibs produced by filling molds with fine powder and heating to solidify. Features low friction resistance for smooth writing feel, with shape flexibility determined by mold feasibility.
• Polyurethane Porous Nib Polyolefin porous nibs with rubber-like softness, excellent bounce-back resilience, and strong alcohol resistance. Primarily used for art brush applications.
• Liquid Liner Applicator Applicators for liquid eyeliner, eyebrow, and lip liner products. Offers nylon tips for soft smooth eye application and PBT brushes with gliding and bounce-back characteristics. Available with both applicator and filter for filter-type components or applicator and ink feeder for free-ink systems.
• Remover Applicator Applicators for make-up remover, corrector pens, and nail care. Available in white tips that show removed color, black tips that conceal removal, and specially coated tips for nail cuticle care with simultaneous oil application.
• Mascara Brush Mascara brushes using newly developed plastic extrusion fiber technology. Softer than existing fibers with unique cross-sectional shape providing superior volume for mascara application.
• Nail Applicator Plastic nibs with hollow interiors and unique cross-sections for nail art applications, and polyester nibs for nail care. Designed for durability required for nail applications.
• Stylus Pen Nib Conductive and non-conductive pen nibs for smartphones and tablets, applicable to both Active (Digital) stylus and Passive (Capacitive) stylus. Customizable shapes and writing feel.
