Cufflinks are jewelry for men worn to keep the cuff on the sleeve closed. Cufflinks can be extravagant, containing diamonds and other precious jewels, or they can be simple and inexpensive.
Cufflinks are made to be used with link cuffs (French cuffs) which have two holes and no buttons. The cuffs can be single or double length and can be worn "kissing" or "barrel-style."
Cufflinks styles come in a wide variety. They come in simple discs that may or may not be connected with a chain. The visible side tends to be larger than the inside part. The visible portion is also typically decorated or monogrammed. Novelty cufflinks are also available.
