I found this while cleaning out my parents' house. It's a used pack of DORCO C cutter replacement blades. I believe they were manufactured and sold in the Showa era. I'm afraid to count them, but there are almost 10 blades. There is some minor rust (see photo 6), but they still seem usable. I'd like to give them to someone who can use them. Approximate size: Replacement blade: Length 10cm x Width 2cm Case: Length 12cm x Width 2.5cm Please understand that these are used and have been stored at home for a long time before purchasing. There are no pets at either my parents' house or my own. I will package them with cushioning material and waterproof measures. I may also use recycled materials for packaging. Thank you for your understanding.
