Here is a link to a great website I found through ebay. I ordered a leather collar from them and it's pretty good quality. I liked that they asked me to send them a measurement of my neck so they could size it properly. The laces in the back are ribbon, which I might change to something stronger for longevity. Enjoy....

Very pretty, and they wholesale, but I'm not sure a lot of folks here would buy them.
