Although cufflinks primarily serve a practical purpose (namely to close unbuttoned shirtsleeves at the wrist), in ancient times, the elite wore them to distinguish themselves from the common people. The custom of manufacturing them in precious metals and sometimes even finishing them with diamonds dates back to that time. On a shirt with double cuffs and without buttons, the cufflink serves to keep the ends of the sleeves together in a stylish way. The cuffs are folded over, then the cufflink is pushed through the holes and fastened.
