I have a Toxonics 3 pin sight in like-new condition. It has 3 .029 wrapped fibers inside of a clear plastic protective housing. It has been mounted on a bow and shot with but you would never know. $35 Shipped in the continental US.

I also have a Cobra Green Mamba release that's been used quite a bit. It's in very good shape but you can tell a lot of arrows have been let go with it. It's very adjustable for small to large hands. The release mechanism is original but the wrist strap has been replaced and is in excellent condition. $25 shipped in the Continental US.
