This is a set of approximately 100 personal information protection seals. (Please note that the exact number may vary slightly.) The size is approximately 13.5cm x 9.5cm, and they are designed to cover an entire postcard. They were included with stock-related documents, and I'd like to offer them to someone who can use them rather than throw them away. They will be shipped via Yu-Packet Post (anonymous shipping). They are unused and in good condition with no noticeable defects, but please understand that they have been stored at home for a long time and were included in mail, so there may be slight color variations or minor edge creases due to the manufacturing lot.
