The biggest kit on this list by piece count: 28 premade slimes plus 48 jars of glitter, animal and cup models, clays, and tools bundled together. Genuinely good for splitting into party favor bags for a whole birthday party, though quality is a bit inconsistent piece to piece, expect a few duds among the 126.

About 126-Piece Slime Making Kit
This kit's real strength is sheer volume: 28 individually packaged premade slimes plus a genuinely wide mix of glitter, clays, and glow-in-the-dark powder to customize with. Reviewers consistently praise the variety and value, and it holds up well as an easy way to build party favor bags without buying dozens of separate slime tubs, one parent specifically described splitting it into 2-3 slimes per guest bag for a birthday party.
The honest tradeoff is consistency: Amazon's own aggregated review data shows durability complaints outnumber praise nearly 3 to 1, some batches arrive dried out, don't activate properly, or tear instead of stretching. Stickiness is also inconsistent batch to batch, some reviewers say it's not sticky at all, others say too sticky. One reviewer also flagged small glass vials containing glitter inside the kit, worth a caution note for younger kids in the 5-plus range since breakage risk isn't addressed in the listing copy.
The Honest Take
What We Like and What We Don't
What we like
- Genuinely huge quantity and variety for the price, the most consistently praised trait across reviews
- Works well specifically for splitting into party favor bags, a recurring real use case, not generic praise
- Includes extras beyond plain slime, glow-in-the-dark powder, clays, and models, that add real replay value
- Strong value-for-money perception repeated across reviews
What holds it back
- Durability is the weakest point, a meaningful share of reviews report units arriving dried out or tearing instead of stretching
- Stickiness is inconsistent batch to batch, not a uniform texture
- At least one reviewer flagged small glass glitter vials inside the kit, worth a caution for younger kids
Is This For You?
Who Should (and Shouldn't) Buy This
Get it if…
Get it if you want one box that covers an entire birthday party's worth of slime favors, and your kid likes mixing and customizing over having one perfect slime.
Skip it if…
Skip it if you're shopping for a single, reliably stretchy slime experience for one child, or consistent quality across every piece matters more to you than sheer quantity.
The verdict
This kit's real strength is sheer volume, dozens of individually packaged premade slimes plus a genuinely wide mix of glitter, clays, and glow-in-the-dark powder to customize with. It holds up as an easy way to build a whole birthday party's worth of favor bags, but expect a few duds among the 126 pieces, durability and stickiness are both inconsistent batch to batch.
What Real Buyers Say
“I used this Slime Kit for my daughter's birthday party and it was perfect. I separated the items and made little favor bags with 2-3 slimes and fun accessories for each guest, the kids loved it.”
United States
“So many little containers, nice to divvy out for birthday party favors. The texture was great, not crazy sticky. Just beware that this will melt into clothes, carpets, and furniture, but it does come out with some scrubbing.”
United States
“This kit is great, good quality slime, but I was personally looking for a more goopy, stretchy slime. It just doesn't stretch very much. If that's what you're looking for, look elsewhere. Overall a solid 4/5.”
United States
“Several of the slimes had to be thrown away because they were dried out, and some never activated properly and were runny.”

Frequently Asked Questions
What ages is this slime kit appropriate for?
The manufacturer's listed age range is 5 to 12 years old. As with any slime kit that includes small parts like glitter jars, beads, and clay pieces, close adult supervision is a good idea for kids on the younger end of that range.
Is the slime non-toxic and free of borax?
The manufacturer states the premade slimes are washable, reusable, and made with quality-tested non-toxic formulas that don't contain borax powder. That's the seller's own claim on the listing rather than an independently verified lab certification.
What exactly comes in the 126 pieces?
28 different premade colored slimes, 48 jars of glitter powder, 8 animal-shaped models, 8 cup models, 6 fishbowl beads, 6 lightweight air-dry clays, 6 foam balls, and assorted accessories, cutting tools, and glow-in-the-dark powder. It's a premade slime and mix-in kit, not a from-scratch glue-and-activator kit, the slime already comes made and the fun is in customizing it.
