I like this skull, I bought it to use as a model for drawing. The only complaint is that the mouth doesn't adjust as well as we'd like; It's spring loaded so you can open it, but it closes by itself. It doesn't stay open where you put it, so I have to find a way to keep it open, which is a bummer. I wish it had a mechanism that would allow you to close and open it as far as you want and stay where you put it. Apart from that everything is alright.
