PURE is a super fine chalk that uses magnesium carbonate obtained by our own production. It is the simplest and most cost-effective model.

By generating from magnesium hydroxide, impurities are suppressed, and excellent magnesium carbonate that is friendly to the environment is used. It is very comfortable to the touch, has little peculiarity, and achieves a high level of sustainability.

The Large Pack has a one way valve on the back that allows air to escape for storage, making it easier to fill fingerprint gaps and preventing friction loss by protecting the pack from drying out.

- Tokyo Powder's magnesium carbonate is purified by reacting magnesium hydroxide, a by-product of salt production, with carbon dioxide. In fact, the production of magnesium carbonate is made by "consuming" carbon dioxide.

Furthermore, a circulation system for seawater-derived resources such as magnesium carbonate is ideal. It is born by synthesizing the raw materials of by-products with by-products, and then returns to the original raw materials. It is an ideal sustainable system.
