This mechanical lead pencil is a collaboration between Kamio Japan and Kuru Toga, and is no ordinary mechanical pencil!
Apart from being kawaii as heck, the famous Kuru Toga rotation mechanism continually rotates the pencil lead as you are writing - stopping your pencil lead from going blunt on just one side as typically happens when using mechanical pencils! A spring-loaded clutch twists the lead bit by bit every time you lift the pencil from the paper. This allows an even wearing of the lead, creating a conical tip shape that provides a fine, consistent line. So clever - and great for drawing!
Takes standard 0.5mm leads.
