My Gf bought me back a little elephant keyring, it's made in the same way but has a little elephant carved inside that bounces around, really crazy. She got it for a really really cheap.
imagine getting like 3 quarters way through one of them, then stuffing it up, you would be so annoyed, amazing they are so cheap, so much effort, but i guess in the end its just a pencil, and just because its awesomly carved, doesnt mean that you would pay a lot for them
