The largest sticker may have lost some of its adhesive strength, as the edge is lifting from the backing sheet. It's a sticker that shines when light is applied. It was not in a bag and has been stored as is. The backing sheet is also creased in several places (the creases avoid the sticker itself, so the sticker is not creased). We are looking forward to your purchase if you understand the condition. Backing sheet size: 11cm wide x 20.5cm long The round stickers are 2.3cm in diameter.
