This is a Sanrio Hello Kitty keychain from the Heisei era, with a retro design. It lights up when shaken, but I haven't replaced the batteries, so I haven't confirmed that it still works. (Please purchase only if you understand this!) It has been stored at home for a long time, so please understand that there may be some age-related deterioration. Recommended for those who collect Heisei retro Sanrio goods. Shipped via anonymous delivery. ✔️ Price negotiations and immediate purchase are welcome!
