Leather / faux leather, feather, tassel earrings: To store, either lay flat or hang on an earring rack. Since they are very lightweight, don't forget to wear the rubber backs to prevent them from falling out. Stud earrings: Always remove before bed. It is best to store them in a sealed bag in your jewelry box. Avoid getting them wet, and also avoid contact with lotions or makeup. I cannot guarantee that these will not irritate or tarnish since every body is different. Please follow the above care instructions to keep your beautiful earrings lasting for years to come!
