These are convenient bottom stops for shortening flat knit zippers. 20 pieces per set Color: Silver I purchased these online out of necessity, but the minimum lot size was 500, and I don't think I'll ever use them all. So, I'm offering them to others who only need a few. I will send them in a small bag containing 20 pieces. I am dividing up a bulk purchase, so I haven't checked the fine quality of each individual piece. Please understand this before purchasing.
