Thank you for viewing. This is a suzuri (inkstone) that came from my parents' house. It says "Tokusen Bunka Suzuri, Genrindo Sei" (Special Selection, Culture Inkstone, made by Genrindo). I don't know the details. Size: Approximately 7.5cm x 13.5cm Weight: 355g I tried washing it, but ink marks still remain. Please check the photos. The box is in poor condition, and there is a name written on the inside of the lid, so I will cover it up before shipping. Thank you.
