Large slime kit with all of the bells and whistles.I have personally tested this product with my kids and the neighbourhood kids.What I like most is that we have so many options.The 6 Neon colours can be mixed to make any colour.Kids really have fun with the colouring and glittering stages.We have also included glow in the dark powder and beads! Absolutely the best value on the market.With this kit you can make up to 10 slimes.I was able to entertain 5 kids for over an hour with just one kit.Our slime crystals can be mixed to make really goopy slime or really snappy slime.Just wait till you see your kid's excitement when they run into the closet to play with with the glow in the dark creation they made all on their own!
