Even when left uncapped, the Markathon Permanent Marker is the only permanent marker that will never dry out. It features a unique injector pump mechanism that restores the ink feed in an instant. Its ink is fade-resistant, water-resistant, and opaque. To refresh, place the cap on the back of the marker and pump until the tip is loaded with ink. Enjoy making a variety of fine and broad lines without risking ink breakage! Chisel tip.
