Lumocolor Whiteboard Marker Refill Blue
Efficient and environmentally safe - that's the idea! Lumocolor pens and markers are easy to refill using STAEDTLER refill stations: Simply insert your marker into the refill station, minutes later it is ready for use, after a few hours it is completely refilled An overfilling is impossible as the pen can only draw its own maximum ink content out of the refill station
