School Series [Slim White Eco-Friendly Dustless Chalk x Chalk Holder Set - Black/White]

Perhaps your impression of chalk is limited to its dusty, chalk-based origins, which can be detrimental to the respiratory system with prolonged use? Nihon Rikagaku Industry, a venerable Japanese brand with a chalk-making heritage, sought to overcome these traditional limitations. They developed dustless chalk by grinding abundant discarded scallop shells from Hokkaido into powder and blending it with natural limestone. Through meticulous crafting, they created chalk that produces minimal dust. The calcium carbonate (from shells) is denser than lime, resulting in significantly less dust during writing and reduced wear. Coupled with thoughtfully designed chalk holders, the writing experience becomes smoother and more comfortable, offering a friendlier option for teachers and students who rely on blackboards daily, as well as for creating eye-catching signage in shops and restaurants! https://live.staticflickr.com/65535/50487732482_705d7299ee_b.jpg Easy to handle and environmentally friendly for students and teachers, these chalks offer vibrant, saturated colors—an excellent choice for drawings and art. https://live.staticflickr.com/65535/50486549081_dcc785ff95_b.jpg Paired with a small blackboard, they can be adapted to any setting, whether in a shop or at home.
