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, fully refilled after a few hours. Overfilling is impossible, as the pen only draws the maximum possible amount of ink from the station. This practical refilling station made of polypropylene (PP) makes it easy and clean to refill Lumocolor pens. Just insert the pen or marker into the refilling station. Capacity: 15 ml. Refilling station for markers 342 / 348.
