This Staedtler Lumocolor Whiteboard Marker (Bullet-Tip) Set Of 4 comes from a range that has been growing for 50 years. It’s perfect for teachers or anyone who uses a whiteboard for presentations or to make notes. The 2mm bullet-tipped markers contain patented alcohol-based ink in bright colours that dries instantly but can be dry wiped from boards without leaving a trace. They're refillable and dry-safe, which means that you can leave the cap off for up to 14 days without them drying out. This set contains four Lumocolor Whiteboard Markers: black, blue, red and green.
