Perfect for St Patrick's Day or just to show your Irish pride, these Guinness cufflinks will add some fun to your formal wear. The perfect gift for an Irishman, your Guinness beer loving friend, or something different for a groom and groomsmen! Guinness cans are attached to a silver toned chain link and bar for easy threading through shirt cuff holes. [Guinness approx. 24mm(h)] Please note: these earrings are NOT waterproof! As they are made from wood and paper, Cheeky Little Monkeys does not recommend getting them wet.
