This is a set of 100 personal information protection seals. The size is approximately 13.5cm x 9.5cm, and they are designed to cover an entire postcard. Please use them for sweepstakes entries or to enclose with return postcards. These were originally included with stock-related documents, but I hate to throw them away, so I'm offering them to someone who can use them. They are unused. They are in good condition with no noticeable defects, but since they were included in mailings, please understand that there may be slight color variations or minor edge creases due to the manufacturing process. I am also selling other personal information protection seals.
