The first move is the smallest one. Press the clasp, lift the ornament, and seat it on another base. About ten seconds by hand, no tools.
Wear a charm as a ring through the working day; move it to a pendant for the evening; let it hang from an ear wire on the weekend. The structure changes around a constant form.
Keep the clasp clean and dry. Do not oil, bend, or force the mechanism — it is designed to be used, often.
