Dome-shaped earrings with beautiful black and teal glitter. - Material: Unknown, but made of shiny metal - Design: Dome-shaped earrings - Back Style: Clip-on closure Thank you for viewing. I'm not sure of the details as these were at my parents' house. I rarely wear earrings, so I hope someone who will use them will consider purchasing them. Please understand that these have been stored at home for a long time.
