NEW Balloon Stickers Soft Balloon Stickers New, unopened set of 4. Although new, these are quite old, so I cannot guarantee the adhesive strength of the stickers. There is yellowing visible from the back. I tried sticking one of mine (from the same era) and it adhered normally. I've included images as a reference, but I cannot offer any guarantees, so please consider them as a reference only. My Melody My Melody My Melo Sanrio SANRIO Fancy Stationery Stationery Sticker
