■ It is the knocking-type that a chalk comes out when you pushed the button on the back (sharp pencil type) (If the button is pressed in the air, the chalk come jump out. Put the chalk holder right before a blackboard of your palm before pressing the button.) ■ You can stick it on a blackboard as it has a magnetic on a cover so a chalk holder is not smeared with chalk powder. ■ It is good for chalks with section diameter of 1.1cm ~1.2cm (good for all products such as Hogoromo, Fulltouch, and Newpoly). However, we do not have a holder for large-size carbonated chalks. ■It is not good for chalks with section diameter less than 1.1cm.
You can use a chalk until it becomes smaller. It is economical as it protects a chalk from getting broken.
It has a cover so it is easy to carry and a pocket does not get messy.
