Monthly CoroCoro Comic Supplement Pocket Monsters Gold & Silver Glitter Stickers These stickers were supplements to CoroCoro Comic from 1999-2000. They have been stored in a dark place since I obtained them. Please note that only Marill is missing. As these are old items, there is a possibility of deterioration over time. Please understand this before purchasing. They will be shipped with measures to prevent water damage and folding.
