Left over from my Ebay jewelry power seller days. Ring stick for measuring the size of a ring ~ measures from size .5 to 15 in quarter size increments, nice groove on the back so the ring doesn't jam on the stick. Ring sizer set from size 1 to 13 in half size increments on a bead chain. I had these in every car I owned for estate and yard sales, auctions, and when I was selling jewelry. Due to fees here the price is firm. JWL TOOL
