This is a very neat light weight chain but the coils have enough space between them that they act like an epilady (pull your hair). I had a chain like this some time ago and loved it but the coils were much tighter and prevented the hair pulling. There are two attachments at the end of the chain. The quick release one broke just from releasing it from the chain the first time. A nice looking chain, as long as you don't mind the hair pulling.
This is an excellent replacement for a cloth lanyard that I'd been using for my USB flash drives. However, be warned that it will grab any hair it gets near (Facial, neck). Also, when taking the lanyard off, it often snags on hair on the top of my head. It is a good, solid product otherwise!
