JA-RU Lab Putty LED Scribbler w/Mini UV Flashlight (1 Unit) Magic Color Changing UV Putty for Kids | Sensory Stress Relief Toy | Mini Slime Party Favors. 9574-1p

Ages ranging from 3-10 this is always a big hit when they get this stuff for their birthdays. All the kids LOVE this. It really is very cool.

I originally bought the UV Color Changing product, but mistakenly received the magnetic putty instead. It was bought for a birthday gift and I did not have time to return it, so we just used what we received and it turned out to be really good putty. The girls I bought them from really enjoyed it. When I reached out to customer service to make them aware of the mix up, they apologized and issued a full refund immediately. Will definitely buy from them in the future.

Just what the kids wanted. Btw don't keep it in a hot car or it will explode!

This stuff is super fun and fantastic.One caveat, if it gets on anything porous- doom! My 3 year old put it on my purse, the carpet, her clothes, my clothes... it suckEd!It was funny finding what looked like bizarre slime all over my purse at work... but after the initial humor of it passed- it was disappointing to discover it’s IMPOSSIBLE to clean up!Give to older kids with lots of warnings that they must ONLY play on hard non porous surfaces or hands ONLY!Super cool that the little light with it changes the color of it— fun for hours! Just be careful!

Such a cool idea! The kids love pressing out the putty and drawing with the light. It really works!

Used for a Christmas scavenger hunt. Fun for all ages.

Awesome!!! Reacts to the uv light and looks amazing. My daughter aka my little mad scientist absolutely loves it!

It is fun for the kids. My nephew loved it!
