Ergonomic, dry-erase markers feature a comfortable triangular barrel for fatigue-free use and a convenient hanging loop on the cap so you don't need a marker tray. Locking tips deliver bright, vivid color ink that is low-odor, nontoxic, washable, and quick-drying. The cap also includes a built-in pocket clip to hang on notebooks and pockets. Use markers on whiteboards, planner and memo boards. The marks can easily be removed with a dry cloth. Stray marks on clothing easily and cleanly wash away. Set includes four colors: red, blue, green and black.
