Circumference of bracelets depends on size selection. For the best fit, measure your wrist with a soft tape measurer and pick the size bracelets that most closely matches your wrist size (rounding up, not down). If you wear a bracelet that is smaller than or exactly the same size as your wrist, it may be tight or cause the elastic to stretch too far, which will weaken it over time. For a looser fit, size up.
The bracelets pictured are varied sizes and are only some of the options you may receive. All bracelets in the set you purchase will be the size you pick or the closest available. All measurements are approximate.
