Price listed is for twenty-four navette brass rim settings. These settings measure about 14mm by 4mm. These set on the stone and go through the front side of the cloth and can be used for flat back or rounded back stones.These are an odd size. I have not found any stones to fit them. Although these are made to go through cloth they can also be used in you jewelry designs. The rim around the stone adds and interesting touch. For jewelry you would have to use flat back stones.
