Get a whiff of this remix Extra Peppy!, Pizza-scented sticker! First there was RETRO, now there's RETRO Remix! We've taken iconic Scratch 'n Sniff Stinky Stickers® designs from the '80s and added a twist: multiple designs, additional messages, and sometimes a new scent. They're SCENT-sational! Fun to collect, trade, and celebrate accomplishments and special occasions.
