Mystery Box contains three (3) - 8oz slimes! Also comes with borax if you would need to reactivate. Things that could possibly be in the Mystery Slime includes but not limited to foam beads, glitter, clay, charms, fishbowl beads, and different colors! You can message me if you have a particular slime you would like included in the box. I say that because we will give you a choice if you are looking to buy for a gift! Smoke free home!
