This is a prototype of my handmade cabochon eyes (12mm). They've been test-fitted at the Mushimushi Cafe, but please note that I haven't tested them on other dolls. I've used printing paper (glossy paper) and resin. This is my first time making cabochon eyes, and they are amateur-made. There may be fine air bubbles, small dust particles, and the possibility of yellowing of the resin or separation of the printing paper due to deterioration. Thank you for your understanding. I have a cat, so please refrain from purchasing if you are concerned.
