These are made for China's doctors, and are made in the traditional style that includes minor imperfections on the jade. Not damage, just part of Chinese medicine culture. The story is included in the information sheet when you purchase two or more gua sha tools. Each is slightly different.
Genuine and natural Chinese jade, the color may be slightly different as they are carved from the stone.
