I definitely was disappointed in my first box for my granddaughter. 3 of the 4 slimes were so sticky that I had to use activator to remove the gunk from her fingers. It said it might be sticky from shipping but it sat in a cool place until my granddaughter could come over and open it. We have ordered before from other slime makers and I'm sorry to say this was the worst. Hopefully it was just a bad batch for the seller, I did read the reviews first and didn't read anyone having this issue but I only read the first few.
