The STAEDTLER refilling station allows for clean and environmentally friendly refills: Place your universal markers in the station, and after a few minutes, they will be ready to write again, and fully filled after a few hours. Overfilling is impossible, as the marker only draws the maximum amount of ink available from the station. After a few minutes, the marker is ready to write again; after 3 to 4 hours, it is completely filled. This practical refilling station made of polypropylene (PP) makes it easy and clean to refill Lumocolor markers. Simply insert the marker into the refilling station. Capacity: 15 ml. For refilling Lumocolor permanent universal markers 313, 314, 317, 318.
