These stud earrings are hand-cut in brass and are a part of the Mackbecks’ Babe Collection. These earrings are supported by hypoallergenic brass posts. Each piece of MackBecks’ jewelry is handmade from start to finish to create an heirloom quality piece. However, the metals do need frequent care to keep their shine. Included with each piece will be a microfiber cloth and it is recommended that you clean between wears. Also, if possible, keep out of humid areas like the bathroom, and definitely remove before showering or swimming.
