This is a very amazing cloud slime . It is just amazing it is very strecthy and drizzly .The color is so pretty.This slime is not edible . I reconmmend slime for ages 7+. If slime arrive sticky it is fine it is not the end of the world I added a little borax packet add it to a cup of warm water and pour it into the slime little by little dont want to over borax. Leakage ,Spillage, Stickyness is not my probelm but i will try my best to help. Hope you purchase.
