School Series Eco-Friendly Dustless Chalk 6 Colors / Slim

Do you associate chalk primarily with its dusty, lime-based origins, and the concern for respiratory health from prolonged use? Rikagaku Industry, a venerable Japanese brand founded on chalk, sought to overcome these traditional limitations. They developed dustless chalk using finely ground scallop shells, a plentiful byproduct from Hokkaido, blended with natural limestone. Through a multi-step process, they created chalk that significantly reduces dust. The calcium carbonate (from scallop shells) is denser than lime, resulting in less airborne dust during writing and a considerably lower rate of wear. This offers a more user-friendly chalk for teachers and students who use blackboards daily, and it's also ideal for creating eye-catching signage for shops and restaurants! https://live.staticflickr.com/65535/50487732482_705d7299ee_b.jpg This chalk is user-friendly and environmentally conscious for schools and educators, featuring vivid, saturated colors that make it an excellent choice for drawings and artwork. https://live.staticflickr.com/65535/50486549081_dcc785ff95_b.jpg Paired with a small blackboard, these chalks can be adapted to any setting, whether at a shop or at home.
