Keep your hands dust-free with this convenient chalk holder. Named "Sharp" after the Japanese word for a mechanical pencil, it works just like a mechanical pencil or clutch knock lead holder. Each push of the top knock button advances the chalk outward in small increments, so the only time you ever have to actually touch the chalk is when you refill the holder with a new piece. Made from tough yet lightweight aluminum and featuring a comfortable rubber grip and chunky design, it is great for use by kids and adults. A faceted ring at the base of the top button keeps the holder from rolling away.
To refill the holder, pull off the top button cap, insert chalk, and put the cap back on.
One piece of white chalk is included. The holder is compatible with standard-sized chalks approximately 11–11.5 mm wide, such as the Rikagaku chalks.
