I ran across a couple of these today - their pretty cool. It enables you to wear your favorite pin as a necklace. This one was in the original packaging but the picture didn't come out too good so I removed - first time out. The bail is large enough to run even a large omega or chain thru it. For now - only one I have unless I find some more. This is the large of the 2 wit the tube mechanis measuring exactly 1" long..
