Kitpas' 6-piece chalk sets are known for being softer, more vibrant in color, and lasting twice as long as conventional chalk.

Kitpas chalks are made from a mixture of limestone-based calcium carbonate and crushed scallop shells. The huge quantities of scallop shells discarded by the fishing industry in Japan have created a major environmental problem and Nihon Rikagaku Industry Co has developed a patented chalk production technique that not only uses scallop shells as a renewable and recycled material, but also creates chalk that is stronger, smoother and more durable.

All Kitpas chalks are made from completely safe and non-toxic materials such as calcium carbonate (found in toothpaste) and scallop shells. The homogeneously mixed particles of what is composed and coated prevent the powder from loosening to avoid conventional chalk dust.

Each set comes with 6 dust-free chalks.

Includes : Yellow, pink, green, blue, violet, white.

Nihon Rikagaku Industry Co has been manufacturing quality art supplies for over 80 years and their most popular products are Kitpas Chalk and Kitpas Art Crayons.
