I stumbled across this
http://www.smallwondersjewelry.com/c...thtml/th01.htm and can't figure out what you would use it for. I understand the thimble sits inside it. Is it just decorative, or would you wear it on a chain and therefore keep it handy for use? But it seems like it would be such a pain, you'd have to take it off the chain in order to open it and remove the thimble. Please, someone explain?
