Where to buy cheap choke chains online?

I don't intend to use them on a animal. I'm making a mascot for my school, it's tail needed to move and the chain acts as a bone. Like how a dog tail swishes and so forth. ...? If I couldn't find a way to make it move like it's real(sure, that's really easy with fake fur...)they were going to use real fur to make it...:( I'd prefer to prevent that. ><
