Care and Usage of Your Suzuri Stone
To avoid unevenness, indentations, and grooves, grind the ink over the entire surface of the stone. Never leave the ink stick on the wet stone surface as it will adhere and damage the stone's surface. Wash the stone in plain water after each use.
To preserve the surface of the stone, it is recommended to wash the stone gently with your fingers.
