Product Description

The regular size of the popular "Dustless Chalk" is the most commonly used in Japanese educational sites, such as schools, prep schools, and study crams. Bright and vivid colors make it perfect for dark rooms, evenings and nighttime use. The main ingredient is calcim carbonated which is also used for toothpaste, so it is safe to use and safe for your body. It can be used more than twice as long as plaster chalk and is economical. In addition, the scallop shells have been successfully recycled, which is a 400,000 tons of disposal in Hokkaido, and the fine powder of scallop shells is formulated to be softer and clearer. The particle is heavy, so it is less likely to shatter dust. The handle is coated to prevent dust from getting on your hands. Shorter chalk shatters and sprinkles in soil, making it a gentle choke for the environment that improves soil. 4 fluorescent colors (fluorescent red, fluorescent yellow, fluorescent green, fluorescent orange) 18 each total: 72 pieces
