The box holds ten round white chalks from JOVI, article 1010 in the Classcolor range. There is a punched window at the front through which you can see the chalks lying inside, and a slot at the top to hang the box up.
Classic school chalk, then: for the board in the classroom, the blackboard in the kitchen, a menu board or the board above a child's desk. It writes softly, wipes off again with a cloth or a board rubber, and snaps neatly into shorter pieces for anyone who prefers something shorter to hold.
JOVI sells the Classcolor range as low-dust chalk: it is said to give off less chalk dust than ordinary school chalk. The chalks are round and of the usual school-chalk thickness.
A cheap top-up for a blackboard, a blackboard sticker or a wall in chalkboard paint, the sort of thing you only miss the moment it runs out.
