On the blackboard!

In contrast to chalks made of gypsum (calcium sulphate), which were used earlier, Jolly only uses calcium carbonate. Real chalk from Jolly is dust-free and easy to wipe off! From the school board to the bistro board, the classic school board chalk is a favourite writing instrument. There is even a practical chalk holder for the round chalk! The 4-edged version of the school chalk is available wrapped or pure as well as in colour!
