I got them for the discovery activity and art project we are doing for the Shark Week class. I'm home schooled so I do quite a lot of stuff like this, this is the third pack of teeth I've received, the first from this seller. I don't think I will buy here again. The instructions are 100% crap and more teeth are broken and chipped than good ones but for what I got it for it should work but it sure could have been better.
