The STAEDTLER refilling station allows for clean and environmentally friendly refills. Simply place your universal pens in the station, and after a few minutes, they will be ready to write again, and fully filled within a few hours. Overfilling is impossible, as the pen only draws the maximum amount of ink available from the station. This practical refilling station made of polypropylene (PP) is designed for easy and clean refilling of the Lumocolor pen. Just insert the pen or marker into the refilling station. Capacity: 15 ml. Refilling station for markers 342 / 348.
