When you think of chalk, you might picture traditional dust-producing sticks made of lime that can be harsh on the respiratory system with prolonged use, right?
Rikagaku Industry, a venerable Japanese brand with a chalkmaking heritage, set out to overcome these shortcomings. They developed dustless chalk by grinding abundant discarded scallop shells from Hokkaido into powder and blending it with natural limestone. Through a multi-step process, they created a chalk where the calcium carbonate (from shells) is denser than lime, significantly reducing dust during writing and also decreasing wear. This innovative chalk offers a gentler experience for students and teachers who use blackboards daily, and it's equally ideal for creating eye-catching signs for shops and restaurants!

This chalk is user-friendly and environmentally conscious for both students and teachers. Its vivid, saturated colors make it an excellent choice for drawing and art.
