Edding T25 black marker refill, 30 ml, is formulated to replenish compatible permanent Edding markers and extend the working life of existing pens.

Supplied as a single 30 ml bottle, the refill is intended for economical top-ups and helps reduce disposable marker waste.

How to use

Allow the ink to distribute to the tip for a few minutes; if necessary, depress the tip gently to encourage flow.

Usage recommendations

Wear gloves and avoid skin contact with ink. Work in a well-ventilated area and keep away from open flame. If ink spills on clothing, treat immediately according to fabric care guidelines. Keep out of reach of children and store tightly closed when not in use.
