It's easy to create beautiful jewelry pieces that are fun to wear with string-on clasps. These clasps feature a silicone grommet lining the stringing hole. Stringing materials slide nicely through the silicone, but the silicone also holds materials securely in place. Thread both ends of your stringing material through opposite ends to create an adjustable necklace or bracelet. These findings work wonderfully with thin chain, leather, and other stringing materials. Browse our selection to find the perfect string-on clasps for your needs.
