10 prs strlng silver medium butterfly earring clasps backs scrolls .925

Please note that the hole size and post - pin thickness varies and there is no standard. How will you know that the butterfly will fit your earrings. Sadly you don't. What we used to have to do for people when we had our bricks and mortar shop was open the hole of each butterfly slightly. This is a tricky procedure and can be done with a pin or needle, but needs extreme caution. If the hole is too big and the post - pin slips through too easily you can only squeeze the butterfly - scroll section and this sometimes grips the post - pin of the earring better. As I said there is no way of ensuring they will fit your earrings.
