It stabilizes at approximately 30°C when the ambient temperature is 10°C, and approximately 37°C when the ambient temperature is 20°C. This helps to shorten the grinding time and disperse fine particles, bringing out the original color of the solid ink. Furthermore, by warming the sumi-ike, it prevents the gelling of the ink solution, allowing you to enjoy calligraphy comfortably. ⸻ 【Condition】 ・Beautiful item, used a few times ・Please note that there may be slight scratches from storage ・Operation confirmed Shipping is planned via Yu-Packet Post.
