This is a bag charm (keychain) by accessory artist Natsuno Niwa, inspired by the image of the galaxy. The chain part shows signs of aging, so you may want to replace it with another keychain if you prefer. Of course, it's still lovely as is, with an antique feel. The pocket watch-shaped charm is beautiful. Here's a comment from the artist: "The background, with its gradation from light blue to deep blue, represents the endless universe. I created this piece with the image of stars circling a blue planet at the center. The sphere at the center contains aurora hologram paper, which sparkles depending on the angle. Also, resin has been layered to create a sense of depth. The rings arranged around the sphere have a special finish that makes them sparkle when they catch the light."
