You are buying a base metal unusual square toggle clasp that is 15x15 mm square with 25 mm long bar. You can use them to fix or craft your jewelry.

Look also for the 6000 charms as well as the other clasps also for sale in my ebay store. I even have charm bracelets and box chains!!This and 75% of my inventory is on sale and on clearance. There are no returns on this item. Please make sure you look and the size and compare it on a ruler. Many items under $20 are small and maybe even tiny. I have a large number of customers that specifically looks for these tiny and small charms and earrings.
