The T 25 refill ink for permanent markers extends the life of almost all edding permanent markers and is an environmentally friendly and cost-saving solution. As soon as the marker is empty, it can be refilled quickly and easily and is immediately ready for use again. The refill ink impresses with its clever drop dosing system, which makes refilling quick and clean. It is permanent, low-odour, waterproof, abrasion-resistant, smudge-proof, lightfast and dries quickly. The ink is ideal for the edding No.1, 370, 390, 400, 500, 550, 800, 850, 2000 C, 2200 C, 3000, 3300 models and for the edding EcoLine 21, 22 and 25. The refill bottle contains 30 ml of ink and does not contain any added xylene or toluene, making it particularly user-friendly. This not only extends the life of the markers, but also protects the environment.
