Shu Prefecture Famous Inkstone I have been using the inkstone after taking it out of its wooden box. When I purchased it, the inkstone fit snugly in the box, but the lid doesn't close properly now, possibly due to aging. Also, there is a line on the inkstone. I'm not sure if it's part of the design, a scratch, a crack, or a pattern, but please be aware of these two points before purchasing. Thank you for looking.
