The loop end of these hoops is wire wrapped, and the other end is an openable hook that matches up to the wire wrapping. The sturdy heavy-gauge wire keeps its shape and stays closed, but is easy enough to open with a good squeeze when you want to add new charms. The hook end can be clipped to shorten, or widened with pliers to feed on hard-to-fit items such as beads. Or, leave it closed and embellish as desired. These hoop components are a stylish way of collecting and wearing your personal talismans and symbols of luck.
