Extra small and extra simple clasp, wich can be put on very thin nylon or wire by everybody without use of any tool. It is especially designed to wear minimalist pendant such as a single pearl or for example the XXS A'Design Award Trophee. With an usual clasp, there is always the restriction of a clasp to large to allow the threading of a very little pendant. XXS clasp, being put after the threading of the pendant suppress this problem. It exists in many size, depending on the link used, from the very thin nylon to thick leather.
