How to use

Attention! Hapstone Premium Diamond stones may seem bald out-of-the-box. This is normal.

Hapstone Premium Diamonds are recommended to be used with water as a lubricant for the best feedback. The diamond does not absorb water. Splash water on the stone's surface. Dry usage is acceptable practice.

Premium Diamond stones do not require any preparations.
