Kicko Glow in the Dark Slime Kit - 12-Pack Slime Toy for Kids in 4.5-Inch Can - Glowing Neon Colors in Green, Blue, Orange, Yellow - Fun Kid Slime as Party Favors, Goody Bag Fillers, or Birthday Gifts

I bought these for party favors for my son's Ghostbuster birthday, and they were a hit! The consistency is really good. Even though it's on the thin side, it still is fun and a good feel. It doesn't leave your hands sticky, but it does leave behind a little moist residue. But nothing that a quick wash of the hands can't fix. I also love that it doesn't stain things. My son threw the slime and it landed on my shoe, but no stain! And it all came up easily so really, that is a big plus considering how much things go flying with a 5 year old. We also love the glow-in-the-dark feature. I think that is what made me choose this slime over other options because it has that little extra. The colors are fun, and they all glow green in the dark so perfect for a Ghostbuster party. Highly recommend this slime!

Nice product for young school age children who like the gooey-ness of slime. It comes in nice colors so kids have a choice of their favorite one. Just know that when the product glows, it does not glow the color of the slime (for example: blue or pink). It's the standard yellow/green color. What I liked most about it is that it's a small amount just right for kid hands-not too much. Would not purchase for really little kids or kids who are prone to putting their fingers in their mouths while playing like thumb suckers. The product glows and those ingredients should not come in contact with their mouths. First grade should be fine, but monitor them. Teach your children to put the slime back in its container and wash their hands after playing with it.

So at first we thought it wouldn’t glow but in order to activate it you can use your phone flash light and just glow it upon the slimes for a few minutes and then you’ll see quite a difference in the dark!Also the texture of the slime is watery and almost like flexible jello but that’s what I expected from the photos. The only thing I wasn’t prepared for was the size, each jar contains enough slime to fill the center of your palm, but honestly I’m still happy about bc my little sister is only 7 and has little hands (I bought it for her).

GREAT

Bought this for the grandkids, second time I order it. We are extremely pleased with the slime, first set they have for 5 months and was still playing with it. I bought some more only cause after 5 months it was 1/2 dog hair and 1/2 slime. The quality of this product is really excellent, if you have ever had poor quality you know that it sticks to everthing or drys out but not the Katzco, it does not stick to anything. I will probably be making a 3rd order in 6 months, the kids love it. Now let me say Kayco customer service is amazing, they keep you up to date from the time you order till it is on your doorstep.

Slime is alright my kids were very disappointed that it didn’t glow in the dark like it says it does!

I bought this multi-pack of slime for my 7 year old, sort of on a whim. Most of Amazon's slime options are underwhelming, and the reviews prove it. Too dry, stains, sticks... I was ready to stop looking and resort to that "build your own" kit where the slime is dependent upon your scientific understanding of slime quantum physics.And then I stumbled upon Katzco's Slime. Good price, great reviews, and plenty of SLIME. So, I clicked the BUY button and crossed my fingers. The slime was at my doorstep 2 days later (thanks Prime) and my daughter was knuckles deep into those little cans of gooey slime.It's wet but not sticky. There's no odor and great consistency. Four colors, 3 jars of each. Oh, and they glow in the dark really well. It's the perfect slime, so quit reading this review and order it. Slimer would be proud...

For Katzco Glow in the Dark Slime. At least six slime products sold on this website have tested for extremely high toxic chemical levels of boron - 15 times as much as is safe! Lab tests were conducted in both America and the European Union, warnings are everywhere. Safe levels of boron in slime should be no more than 300 mg/kg/ppm (parts per measure). Lab testing showed that the six tested slime products sold here contain boron measured at 4700, 4600, 1900, 1500, 1400, 1100 mg/kg/ppm!! Unbelievably over the safe limit of 300!Another slime's packaging looks like the Katsco slime packaging - same box, photo, starts with a 'K', ends with an 'o', just with an 'idsc' in the middle. Boron measures at a whopping 4600. Another one starts with a K', ends with 'roo'. It has the highest level of boron - 4700. Read reports for yourself - in America, U.S. PIRG 's "WINTER 2018 NEWS BRIEFS", 'Trouble in Toyland - 2018 33rd Annual Toy Safety Report". They write, "We found slimes with boron concentrations that are as much as 15 times the European Union’s limit. Ingesting boron or borax can cause nausea, vomiting and long-term reproductive health issues. Jordan, Canada and other countries have taken action to limit or ban slimes with high boron content." On December 13, 2018, media in England reported, "Many popular slime toys may contain higher than recommended levels of a potentially harmful chemical – and nearly half do not meet the EU safety standard, according to new research. Another product, classified as a putty, also failed the test. Short-term over-exposure to the chemical can cause skin irritation, diarrhoea, vomiting and cramps, according to experts. Borax – a compound of boron – is part of the product’s makeup, due to its ability to increase “stickiness”. Safety directives outline that liquid or sticky toys should contain no more than 300mg/kg of boron. Exposure to large amounts of boron can affect the stomach, brain, liver, kidney and intestines and may eventually lead to death. It may also affect fertility and could harm unborn children, according to the European Commission. "I am returning the Katzco Glow-in-the-Dark Slime I purchased for my grandkids' stocking stuffer. Who is policing the sale of toxic items?!
