School Series Eco-Friendly Dustless Chalk / Fluorescent Colors

When you think of chalk, you might recall the dusty, lime-based sticks that could be harsh on the respiratory system with prolonged use. Rikagaku Industry, a long-standing Japanese brand that began with chalk, developed these dustless chalks to overcome the drawbacks of traditional ones. They grind discarded scallop shells from Hokkaido into powder, which then undergoes a multi-step process to create dustless chalk. The calcium carbonate (from shells) is denser than lime, so writing produces significantly less dust and the chalk wears down more slowly. This makes them a gentler, newer type of chalk, ideal for teachers and students who spend a lot of time writing on blackboards, and also well-suited for creating eye-catching signs for shops and restaurants. With their bright, vivid fluorescent colors, stationery lovers won't want to miss out on this rare palette! https://live.staticflickr.com/65535/51206628858_cb6acab56b_b.jpg https://live.staticflickr.com/65535/50487732482_705d7299ee_b.jpg A great choice for drawing and art, these chalks offer saturated, vibrant colors that are easy and pleasant for students and teachers to use in school environments. https://live.staticflickr.com/65535/50486549081_dcc785ff95_b.jpg Paired with a small blackboard, they can be used to create ambiance for any occasion, such as birthday celebrations, whether at a shop or at home.
