Beadnova Pattern Style Gold Plated Brass Bead Tips Clam Shell Clamp on Double Loop with Acrylic Jar 4mm 50pcs Matel / Color: Brass with Gold Plated Size: Approximately 4mm with 1 mm Hole Quantity: 50pcs with Acrylic Jar Bead tips are great for use with silk and other bead stringing threads. We DO NOT recommend you use them on bracelets. Bracelets get much harder wear than a necklace, and the loop end of the bead tips are quite flexible and could come undone more easily on a bracelet.
