This is a brooch that lights up with a button battery, purchased at an aquarium somewhere a long time ago. It has been stored at home for many years without being used, so it looks clean, but I cannot guarantee that it will light up. It's possible it might light up if you replace the button battery, so I'm listing it as junk. The included button battery has not been used for many years and I think it no longer functions. For those who don't mind if it doesn't light up, and for those who don't mind it being a junk item. I will wrap it in bubble wrap and ship it via Yu-Packet Post Mini.
