Inconsistent slime
3 out of 5 stars
Inconsistent slime
Roughly 1/2 of the slime is not a good consistency. The green, red and yellow colors seem to have issues but the pink, blue and purple were great. You can see in the photos that yellow was totally solid. The customer service of the company is super fast and responsive so that’s why I leaned to more stars. The packaging is also cute.

    Received plastic, not slime. They were all dried out. Slime honestly isn't the best toy for toddlers but this one is especially dangerous because the tiny tiny "glitter" pieces fall right odd the dried out "slime". Returning immediately. Absolutely horrible.
