Rikagaku White Dustless Chalk, 6-Pieces (DCC-6-W)

Includes six pieces of purple chalk. Do you remember the old school days where you would hit a chalkboard eraser on the board and “Pouff!” out comes a cloud of white dust? This new chalk addresses that problem with its natural calcium carbonate composition made from scallop shells. The particles are heavier, creating less dust. In addition, the calcium carbonate lasts twice as long as chalk plaster, making them more economical.
