Magnetic Slime Putty, Magnetic Space Putty Slime with Upgraded Magnet Toys for Kids Adults, Fidget Toy Stress Reliever Puddy for Christmas Birthday Gifts Stocking Stuffers (2 Pack, Blue&Black)

We've had tons of magnetic slimes in the past and they don't really react, but these ones do! You can visibly see the slime "sucking" in the magnet when you set it on top. The kiddo loves making time lapse videos of it! Don't get the magnets stuck together though, because they are strong and hard to remove.

My kids really like this. It's a little expensive, but is cool and fun to use.

I bought a 2 pack, blue and silver. They are very hard. I guess you need to warm it up for the putty to actually ‘pull’ to a magnet but I don’t want to put it in water nor the microwave because of what’s in it. We’ve rolled it in our hands for a while to ‘work it’ but it’s useless.

I gave this as an "emergency gift" to plus-ones at a Christmas party. As others have noted, the magnet is the square cube, and the putty contains the metal, so unfortunately it will not stick to your fridge. It was a wildly popular gift, though, and I would recommend it for children or adults. Note that dirt or oil (or food) will stain the putty.

The putty was disappointing to say the least. We bought it for my daughter to split & give one to a school friend for the holidays & keep one for herself. We opened the silver (we got silver & blue) - it was hard as a rock. Not putty like at all. I put it in a ziploc bag and submerged it into a cup of boiling water for about 15 mins. It was then at least more putty like and malleable - however it wasn’t the fluid type of putty it shows in the pictures. Also - nothing we received said we would have to submerge it into boiling water to get it to putty consistency. All in all - I do not recommend. Once warmed it’s a decent fidget, but the magnet is pretty worthless due to the lack of fluid consistency.

My 9yo loves this!

The suction power of the slime makes the container very difficult to open, even for an adult, and even after the first time. It is hard enough that I started dreading being asked to open it. Fun product, you will want another magnet to fully utilize it.
