With 91+ reviews and a 4.4-star average, these earn high marks for quality and kid appeal.
"Daughter loves it, had lots of fun with the slimes."
"Really nice quality slimes. My kiddo loved this."
"Amazing quality! Amazing add ins! Best slime I've purchased yet for my kids and they loved it"
"The slimes smell good and are fun for everyone. The little add ins make each one unique and extra fun"
"The slime sticks to literally everything and ruined my couch cover when the baby dropped slime on it."
Most parents say the quality and add-ins are the standout, though one reviewer had a rough time with slime on fabric, so keep it away from couches and carpets. Heads up that this isn't for small children, there are lots of little pieces that could be a choking hazard.
