Marker refill Edding BTK-25 Green 25 ml

The Edding BTK-25 Green 25 ml refill restores dried whiteboard markers by replenishing their ink. The 25 ml bottle uses a capillary refill system that allows clean and precise refilling of almost all Edding whiteboard markers. Available in green (also offered in black, red and blue), the refill contains no added butyl acetate and is made in Germany.

Advantages

The capillary system enables simple, spill-minimised refilling by placing the marker nib into the bottle. A 25 ml volume extends marker lifetime, reduces waste and lowers replacement costs. The formula is suitable for whiteboard surfaces and provides reliable, long-lasting colour performance.
