Chinese stamps. I don't know if they can be used. Please check the photos for details. This is a collection of my stamp-loving father. They have been stored at home for a long time after purchase. There are yellowing, corner wear, and folds due to aging. There are also ink stains in places. Please understand that these are used items. ● Sold as a set, no individual sales. ● Please refrain from negotiating discounts. ● Immediate purchase is welcome. We will prioritize the person who purchases first, even if there are comments. Thank you for your understanding.
