This is a natural stone Ogatsu Suzuri (inkstone) from Michinoku Miyagi, made by a craftsman. Ogatsu Suzuri has been famous as a renowned producer of high-quality inkstones since the time of the Sendai Date clan's rule. It once boasted the largest production volume in Japan, significantly supporting the finances of the Sendai Date clan. It's a wonderful production area that remains popular, and is still highly regarded as a fine inkstone, with many fans. I will be offering this at a reasonable price. How about this price?
