This is a non-sale item that came as a prize with Suntory beverages. I'm not certain, but I think I've used them a few times each. Since many years have passed, the adhesive may have weakened, but I'm selling them as is without testing. Please be aware of this. I don't see any stains or fading in my subjective opinion, so they are also recommended for collectors! I'm also selling masking tape and stickers. I'll offer a discount for bulk purchases, so please comment! Pattern/Design...Character Moomin
