24 days of squishy surprises

This advent calendar swaps candy for slime, with a new surprise behind each of its 24 doors. Kids find butter, cloud, glitter, foam, glossy, bingsu and two-tone slime, along with 40+ mix-ins like charms, sprinkles and clay slices to make every batch their own. There are 12 colorful slime pots in all, so every day of December brings something to stretch, squish and swirl. Made with kid-friendly materials for ages 4-12. Slime is not edible, so wash hands before and after play.
