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, fully filled after a few hours. Overfilling is impossible, as the marker only draws the maximum amount of ink available from the station. This practical refilling station made of polypropylene (PP) allows for easy and clean refilling of the Lumocolor markers. Simply insert the marker or pen into the refilling station. Capacity: 15 ml. For refilling Lumocolor permanent universal markers 313, 314, 317, 318.
