Vintage Lot of Trend Scratch and Sniff Stickers Celebrate Party Bear Mouse Scent

Lot of of four vintage TREND Scratch 'n Sniff Stickers. Three have mouse design and a chocolate (?) scent. The other has a bear and cake-like smell. Have some scent; the mouse ones are fainter. Since these are vintage stickers, I cannot guarantee the stickiness or scent strength but I will note if I notice any issues.
