Used masking tape. It's old and in poor condition. Please check the images carefully. The Miffy flake seals have bent edges. These are items I was about to throw away, so please only purchase if you understand this. They will be put in a plastic bag and shipped in an envelope. (If you prefer, I can use a recycled box. Please let me know after purchase.) I will remove this listing in a few days due to bulkiness.
