One Neuland Refill Ink bottle will refuel your marker approximately 11 to 45 times depending on Markers size. (11 x Neuland Big One markers, 22 x Neuland Number One markers, 45 x FineOne markers).
We encourage you to reuse these tools, as they have been designed with this in mind. Not only will you limit waste, you will also save money in the process. Sustainability is embedded in the design of all Neuland products and the Refill Ink bottle is at the center of the recycling process.
