This original design has been laser cut out of a mix of glitter, mirror, and opaque 1/8" acrylic sheets and is backed with white acrylic. The pendants measure 2.5" wide by 1.75" tall. They hang from gold earring hooks. If you are interested in studs, clip-ons, or wrap around hooks for stretched ears, please let us know in the "Notes to Seller" section when you check out. We love these earrings and think that they never get old. However, to prolong the life of yours, treat it with love! Be careful when storing it in a bag or pocket so that it does not break. Also, avoid getting any and all jewelry wet. Take it off and keep it out of the way of all showers, baths, pools, hot tubs, saunas, and sensory deprivation tanks.
