All of the bracelets are tie on & glass beaded. You can tie it twice or even three times to make the cord shorter. The beads are 9mm glass beads, on a gold or silver cord with end clasps. Each bracelet has 28 beads. If you think you need it a little bigger, I can customize & add more beads. The natural stone beads are 7.5 mm beads. All of my cords are one size fits all. Simply tie a knot twice or three times. Since all of the beads are handmade glass beads they are all different in shape or shade. Colors may vary from what is in the picture. The matte gold beads are painted glass. I would also recommend not going in the water with the bracelets because of the cord. Every bracelet is made with lots of ❤️. They look great alone & also look great with many! Big Rainbow Bead Bracelet, Tie On Bracelet & Necklace, Glass Pony Beads, Summer 2020 Trend, Large Colorful Beads
