Schylling Nee Doh Nice Cube Squish Toy, ages 3+ (purple), 1ct

This thing is honestly so cool and fun to play with - but it was PRICEY. Not saying it wasn't worth it exactly, just that I would have preferred to spend less. But being a trendy item and hard to find, I get that the price is reflective of that. It really does go straight back to the cube shape, and is very sturdy. I think it would be difficult to pop the thing, even if you tried. It gets softer the more you play with it, but then as it "cools down" it gets a little more firm again. It washes up nicely, but doesn't go back to the clear/glossy look it has right out of the box. The kiddo (11M) loves it, and hardly put it down the first couple days. I love it too, and if it was a little bit less $$$ I would probably order myself one. As it is, I'll just wait for him to tire of it!
