Please note that not all types of beads are used in every bracelet. This product is not suitable for those with metal allergies. The elastic thread used is polyurethane (double-layered). The thread will be replaced before shipping. Inner circumference: Approximately 15cm (approximate measurement, may vary slightly) Size adjustments are only available for smaller sizes. If you know your approximate wrist size before purchasing, please let me know in the comments. Shipping will be via Yu-Packet Post Mini. This is a set of 3 items as shown in the image. (+ with a bonus) Recommended for gifts(*´꒳`*) Accessories are not included. The beads are imported from overseas, so they may have minor scratches. I try to photograph the items to show the colors as closely as possible to the actual colors, but the colors may differ slightly when you receive them. These are handmade items, so please purchase only if you understand and agree to this. jojo nana Genius President
