This is from the artist aiueo-san. I believe it cost between 2000 and 3000 yen. I only tried it on, and then stored it in a dark place. However, due to the use of resin (?), and being handmade, there are air bubbles and a slight stickiness on the surface. The metal parts also have some tarnish. I am also selling other earrings from this artist. *Please refrain from purchasing if you are sensitive to such issues.*
