NATIONAL GEOGRAPHIC Glow-in-The-Dark Putty Kit - Use The Uv Light to Draw Fun Designs!

It was great

[ETA months later: the only drawback to this toy is that the child must have clean hands to play with it! It can get very gross and brown and lose its glowy properties if your child plays with it on a dirty floor or with dirty hands.]My son loves this product. It is not wet or gooey, and so he doesn't mind touching it, which is not the case with most goo-based toys. He has sensory issues relating to wet/wet-appearing things, so it was a wonder that he just picked this up and started playing with it. It has a lovely easy glow - it only takes a few minutes under a direct light source for it to start glowing really well. It holds together but isn't hard to manipulate and lasts quite awhile so the child can play in the dark with it for some time before the glow fades. And my son loved the little light that came with it, that you can use to make patterns in the putty. All in all very fun.

I bought this for my 10 yo son as a gift. He loves it and uses it when he needs a “brain break” when doing homework or using the PC.

My Neice loves this stuff. This was a Christmas gift and it she can’t get enough of it.
