Sarasati Cotton 100 Fragrance-Free Panty Liners, 224 Sheets

Specifications

Features

100% Natural Cotton Surface: High-quality natural cotton with rounded fiber tips. Softer contact with skin than synthetic liners. Gentle on sensitive and delicate-zone skin.

No-Binder Manufacturing Method: Surface sheet woven with water only — no adhesives used. The no-binder method means no glue-based compounds contact delicate skin during wear.

Fluffy Air-Filled Sheet: The fluffy surface sheet contains air pockets that reduce friction and distribute pressure. Less rubbing against sensitive skin during extended daily wear.

Fully Breathable Back Sheet: Back material allows moisture and air to escape to the outside, reducing heat and stuffiness around the delicate zone throughout the day.

Fragrance-Free: No added scents or perfumes. Suitable for those sensitive to fragrance or who prefer unscented daily products. Nothing added to trigger sensitivity reactions.

Japan Cotton Mark Certified: Carries Japan's Cotton Mark — external certification given only to products made with qualifying high-quality natural cotton materials produced in Japan.

Benefits

: The combination of rounded cotton fibers and the fluffy air-filled structure means the liner sits against skin without the scraping sensation common in synthetic liners. Verified for daily wear.

: The no-binder surface means the layer touching your skin was made without chemical adhesives. You get cotton contact without the compounds conventional manufacturing methods leave behind.

: The fully breathable back sheet lets heat and moisture escape outward. Panty liners that trap heat cause discomfort — this one is designed not to.

: No added fragrance means nothing triggering a sensitivity reaction. For those who wear liners daily, removing fragrance from the equation simplifies what touches their most sensitive skin.

: At 224 sheets in one purchase, this is a stock-up pack designed for daily liner users. You are not buying 30 sheets and reordering within two weeks.

: Kobayashi is a recognized Japanese healthcare company. The Japan Cotton Mark is an external certification, not a marketing claim — it requires the product to actually use qualifying natural cotton.

How to Use

Peel the protective sheet from the adhesive side of the liner.

Attach firmly to the center of the crotch area of your underwear.

Replace with a fresh liner when damp or as needed throughout the day.

Dispose of used liners in the trash — do not flush.

For best results, replace every 3–8 hours depending on personal preference and activity level.

Product Story

Sarasati is Kobayashi Pharmaceutical's feminine care liner brand, known in Japan for its emphasis on natural cotton construction. Kobayashi Pharmaceutical is a Tokyo-based healthcare company that has been producing daily hygiene products for the Japanese market since 1886 — over 130 years of product history. Their approach with Sarasati focused on what the surface layer directly contacts skin is made of, leading to the 100% natural cotton construction that distinguishes the line.

The Cotton 100 series focuses specifically on the no-binder manufacturing method — a production technique where fibers are woven using water only rather than conventional adhesive binders. For a product worn against sensitive skin for hours each day, the elimination of adhesive compounds from the surface layer represents a deliberate engineering choice rather than a marketing claim.

The Japan Cotton Mark certification is an external standard maintained by the Japan Cotton Promotion Council, not a self-awarded designation. Its presence on Sarasati Cotton 100 confirms that the cotton used meets the Council's material and manufacturing requirements.
