Made small for ease of use. Comes in a value pack of 4. ■ Small Suzu-yo Doro Toishi (Mud Whetstone) - 4 pieces per bag - For cleaning Endei, Uhatake, and Ogatsu suzuri (inkstones) Photos are for multiple listings, so they are reused. Approximately 2cm x 4.5cm, 4 pieces per bag. A size that is easy to use even for small inkstones. As it is a natural whetstone, cracks and chips may be mixed in. Please understand. The feeling of use is that it is fine-grained yet firm, and it dissolves moderately to become mud. Additional bags are 1180 yen each. Please inquire. This product is made by cutting the part suitable for inkstone whetstones from a large stone layer. It has a fine texture and does not contain much hard foreign matter. I use it like a inkstone cleaner every time because I use light ink. Just fill the inkstone with water and grind it with the mud whetstone. It's the same way you grind ink.
