It appears to have been purchased in 1989 (the first year of the Heisei era). I think it's in good condition, with no noticeable stains. Please note that there is handwritten text on the underside of the wooden box lid that says "Purchased in ○○ year," etc. Depth is approximately 20 cm. ☆ I am listing various old items. I will offer a discount for combined purchases. ☆
