A striking set of nose studs, this 5 pack feature square cz crystals instead of the traditional round, giving them that little bit of edge. Each stud weighs just 0.1g and has a ball end, so you simply insert it into your nose and the ridged ball keeps it in place. The square crystal is 2mm in size and sits on the end of a 7mm long, 24ga stud. it's made of sterling silver and has a 925 stamp.
