While I was at FFF this weekend, I ran across a very interesting vendor who creates custom BDSM oriented jewelry. While I didn’t purchase anything from him this weekend, I had a good discussion and carefully inspected the goods he had on display. Symbolic Treasures was the name of the store. They specialize in custom work, and can create a wide variety of items. The thing he was most proud of was a heart shaped lock that he created. It was very sturdy, I tried to pull it appart, and couldn’t get it to budge with just my hands.
He had a couple of very delicate, artistic collars on display as well, so this is another option for those who want a more sophisticated collar for their slave.
I liked this guy’s work, and while his stuff isn’t cheap, I think it is reasonably priced for sterling silver.
Check him out.
