Can you suggest some good websites for non-leather belts?

I am specifically looking for pyramid studded belts as these are the only kinds of belts I like to wear. However, most of the belts of these kinds are made from leather. I admit that I have a few of these leather belts myself but I bought them before I was making a conscious effort to buy non-leather belts. I’m having trouble finding a website that has these belts made from non-leather materials. Since these are something of an odd item, if you can link me to any sites that sell non-leather belts, I’d be very grateful to have a starting off point.

Note: I have tried googling non-leather belts but I figure the collective might have more comprehensive answers.
