off the cuff ......

A cufflink (also cuff link or cuff-link) is a decorative fastener worn by men or women to fasten the two sides of the cuff on a dress shirt or blouse.

Cufflinks are designed only for use with link cuffs (also known as French Cuffs), which have buttonholes on both sides but no buttons. These may be either single or double-length ("French") cuffs, and may be worn either “kissing,” with the ends pinched together, or “barrel-style,” with one end overlapping the other. Kissing cuffs are usually preferred.
