All three clasps were struck in yellow copper zinc alloy and have a frame with an inside edge that resembles the perforated edge of a postage stamp. They are inscribed "NORTH AFRICA 1942–43", "8th ARMY" and "1st ARMY" respectively and were designed to be sewn onto the medal's ribbon. Regulations only allow one clasp, the first earned, to be worn with the Star. When the ribbon is worn alone, a silver Arabic numeral "8", numeral "1" or rosette is worn on the ribbon bar to denote the award of the respective clasp.
