It's a single-handed operation. For a box clasp, all you have to do is align the tongue to the housing, apply light pressure, and click. It's one of the more accessible fine jewelry closures without trading away the security.
The Perfect Fit
When sizing bangle bracelets, the inner diameter is the relevant measurement. Typical measurements such as small, medium, and large are based on standard hand circumference ranges. If you are buying as a gift without precise measurements, hinged or adjustable bangles offer considerably more fit flexibility than a fixed-diameter slip-on style.
Made With Purpose
Security in jewelry is largely a question of intent. A well-made hinged closure distinguishes between the accidental force of everyday movement and the deliberate pressure needed to release it, and responds accordingly.
