Cufflinks are items of jewelry that are used to secure the cuffs of dress shirts. Cufflinks can be manufactured from a variety of different materials, such as glass, stone, leather, metal, precious metal or combinations of these. Securing of the cufflinks is usually achieved via toggles or reverses based on the design of the front section, which can be folded into position. There are also variants with chains or a rigid, bent rear section. The front sections of the cufflinks can be decorated with gemstones, inlays, inset material or enamel and designed in two or three-dimensional forms.
