Erasable gel ink refill PILOT Pilot FriXion BLS-FR7-BN-S3 brown for FriXion Ball/Slim/Clicker

The PILOT FriXion BLS-FR7-BN-S3 brown erasable gel ink refill is a set of three medium-point refill cartridges designed for use with FriXion Ball, FriXion Slim and FriXion Clicker rollerball pens. The refills use thermo-sensitive gel ink that becomes invisible when warmed by friction, allowing written lines to be erased cleanly without abrasive erasers. These brown refills are intended for everyday writing, note-taking and on-the-fly corrections where temporary or editable ink is preferred.

Advantages

Thermo-sensitive gel formulation enables smooth, consistent writing with the option to erase by friction; compatible with multiple FriXion pen models to extend pen life and reduce waste; medium-point performance for clear legibility and balanced line width; brown ink provides an alternative to standard black or blue for organizing notes, color-coding and softer visual contrast on printed or handwritten materials.

Suitable for

• Everyday handwriting and note-taking
• Drafting, editing and corrections in planners or notebooks
• Color-coding and visual organization of notes
• Temporary annotations that will be removed later

Key specifications

• Ink type: thermo-sensitive erasable gel ink
• Color: brown
• Point size: medium (standard medium rollerball line width)
• Pack quantity: set of three refill cartridges
• Compatibility: designed for FriXion Ball, FriXion Slim and FriXion Clicker rollerball pens

How to use

Insert the refill into a compatible FriXion Ball, FriXion Slim or FriXion Clicker pen according to the pen manufacturer’s refill replacement instructions. Write as with any gel rollerball; to erase, rub the written area with the pen’s built-in eraser or another friction eraser until the ink becomes invisible. If needed, rewrite immediately after erasing, as the surface returns to a state suitable for fresh ink.

Usage recommendations

Store refills at room temperature and avoid exposing written material to high heat for prolonged periods, because thermo-sensitive ink can fade or become invisible when heated. For archival or long-term documents, choose permanent ink alternatives rather than erasable refills.
