The Best Borax-Free Slime Kits (Under $25) on Amazon in 2018

Slime kits are an easy way to make slime at home, but you can make slime without a kit.

A simple slime recipe has three ingredients: white glue, baking soda and saline. Other household items can be used for special effects. Shaving cream makes slime fluffy. Food-dye gives slime color. There are thousands of slime tutorials and ideas on YouTube and Instagram if you’re looking for inspiration. 

That said, slime kits have two advantages over a do-it-yourself approach:

  1. A slime kit is more giftable than raw materials; and

  2. Slime kits have ingredients for special effects (e.g. glow-in-the-dark slime).

Are slime kits safe? It depends on the kit and the person who is using it. Many slime kits contain Borax, an irritant that may have toxic effects on the body.

There are slime kits without Borax, but even so, some parents don't want their kids touching glue or food dyes. It's up to parents to decide what is or isn't acceptable for their children.

Here are the best-reviewed (Borax-free) slime kits selling on Amazon for less than $25:

Avg. Price: $25 | Bargain Price: $20

Many Amazon customers agree that this kit makes great slime, but several reviewers (even happy ones) were frustrated by the kit's lack of instructions and labeling. Be prepared to look online for slime-making dosages if you buy this kit.


Sorry, that's all I have for now. Most slime kits contain Borax. If you opt for one, be aware that powdered Borax is more dangerous than Borax that has been diluted in water.
