Minnie Mouse light-up ring purchased at Tokyo Disneyland. ⚫︎ Made of plastic, so it's not adjustable. ⚫︎ Inner circumference is about 13.5cm. ⚫︎ Batteries still have some life, so it can be used as is. Please refrain from bidding if you are nervous about the condition or are seeking perfection, as it has been stored at home. Please read my profile. No claims, no returns!!
