3x11mm fold-over clasps for jewelry making. Plated brass. Antiqued copper plate has been darkened to provide a "distressed" appearance. Fold-over clasps operate on a hinge, similar to the closures on some wrist watches. Fold over clasps are popular for bracelets and watches because they can be clasped with one hand. Carefully close open loop around jump ring; clasp may not stay closed if loop is bent too far.
