Do you remember the old school days where you would hit a chalkboard eraser on the board and “puff!” out comes a cloud of white dust? This new chalk addresses that problem with its natural calcium carbonate composition made from scallop shells. In addition, the calcium carbonate lasts twice as long as chalk plaster, making them more economical. Think of it as triple-milled soaps that lasts and lasts. This chalk doesn't break down easily.
This is probably the best quality chalk we have ever used. Exclusive to Jaq Jaq Bird's line, we love the quality. Dust free, our chalk comes in 5 colors. Made in Japan. |
