School Series 【Slim 6-Color Eco-Friendly Dustless Chalk x Chalk Holder Set - Black/White】

Do you associate chalk with dusty, respiratory-irritating lime-based sticks? Nihon Rikagaku Industry, a long-standing Japanese brand that started with chalk, has overcome the drawbacks of traditional chalk. They grind abundant discarded scallop shells from Hokkaido into powder and mix it with natural limestone to create dustless chalk. Calcium carbonate (from shells) is heavier than lime, so writing with it produces minimal dust and significantly reduces wear. Paired with stylish chalk holders, they offer a smoother, more comfortable writing experience. This makes them a friendlier option for teachers and students who use chalkboards frequently, and also perfect for drawing signs in shops and restaurants! https://live.staticflickr.com/65535/50487732482_705d7299ee_b.jpg User-friendly and environmentally conscious for schools and educators. Vibrant, saturated colors make them a great choice for drawing and art. https://live.staticflickr.com/65535/50486549081_dcc785ff95_b.jpg Paired with a small blackboard, these can be adapted for various settings at home or in a shop, perfect for creating atmosphere during celebrations like birthdays.
