Crazy Aaron's Hypercolor Thinking Putty

This Hypercolor Thinking Putty is a super fun toy. The color really does change, and it's held up well. My daughter has had the Epic Amethyst version for over half a year now and it hasn't gone stale at all. It hasn't stained her hands either, which I really appreciate. I know putty like this can stain or get stuck in carpet if you're not careful, but we haven't had that issue. It does develop a bit of an odor after longer use, which is kind of gross, but putty can be that way sometimes so it's not a big deal. The tin it comes in is nice and durable. I got this for my daughter's Christmas stocking last year, and she loves it. She's a big fan of Crazy Aaron's and has collected a bunch of different versions.
