Hi and Welcome to Cherrygon's Beading Gallery. This a U Pick Lot of Vintage Screw Barrel Clasps. They are several sizes and colors available. Screw Cap finish is secure.  They all have rings to attach to   your project or u can remove the Rings as we do and start your stringing medium from there. We do that so there is less chance of Your Project breaking and coming apart from the clasp its self.  This is a great little Secure Clasp for all your goodies costume offerings.  The Starting Inventory is Below with the details.

Thanks for Stopping By and Happy Beading! Check out the rest of my Unusal Goodies.  Shipping and Handling Free USA.  Thank You Again for supporting this one woman small shop.
