This is a sound-making sticker. The backing sheet and the sticker in the lower right corner are missing. There is some dirt on the adhesive surface on the back, but it still has adhesive strength.

The sound plays when pressed repeatedly. #HeiseiRetro #HeiseiRetroSticker It will be placed in a clear pocket, wrapped in bubble wrap, sandwiched between cardboard, and shipped.
