These aren't your average chalks. kitpas has been crafting art-quality chalk in Japan since 1937, and their secret ingredient is surprisingly beautiful: recycled scallop shells.

Sourced from Bibai-shi, Hokkaido ("beautiful shell city"), the powdered shells are blended with calcium carbonate in a patented process that reduces waste and produces a noticeably superior chalk. Smoother lines, richer color, minimal dust, and easy, clean erasing.

Over 60% of Japanese schools use kitpas. Now your chalkboard wall or slate can, too.

Non-toxic, allergy-safe (no dairy or egg), and certified CE, CPSIA, and ASTM AP. Includes 12 colors: classic whites, brights, and fluorescent hues for a little extra fun.
