Here at Hyper Cosmic, you can guess that we like space. I mean, obviously personal space, but this is the final frontier kind. These are a modern twist on the vintage sun and moon, engraved with cute little faces on mirrored acrylic. These hang on nickel-free earring hooks and the sun measures at 1.5" in diameter, and the moon is about 1.5" tall and 1" wide. They're available in both gold and silver.
