Do you remember the old school days where you would hit a chalkboard eraser on the board and “Pouff!” out comes a cloud of white dust? This new chalk addresses that problem with its natural calcium carbonate composition made from scallop shells. The particles are heavier, creating less dust. In addition, the calcium carbonate lasts twice as long as chalk plaster, making them more economical. JetPens finds dust still gets on your fingers when using this chalk, but is not as airborne as standard chalk. We are dedicated to providing our teacher customers with healthier, more fun writing alternatives!

The manufacturer of this product, Japan Rikagaku Industry, was established in 1937 on the belief that every human being needs to “be loved, be useful, be praised and be needed”. The company chose to manufacture chalk made from calcium carbonate because there was an indication that teachers who used chalk had a higher probability of tuberculosis than others. In 1953, the resulting dustless chalk was the only one approved by the Educational Ministry of Japan. In their two factories, Rikagaku employs people often overlooked by society. In the Kawasaki factory, there are 48 employees in total: 22 severe mentally-disabled people and 9 mildly mentally disabled people. In the Misaki factory, there are 28 employees in total: 13 severe mentally-disabled people and 9 mildly mentally disabled people. The company has a model blend of environmental and people friendly management policies.

I can't say these are fluorescent when you write with them, but I absolutely love them. They don't give you the nasty chalky feeling when you write with them. I don't know how they managed to do that, but it's wonderful. I'll be getting more when I run out for sure.
