Thank you for viewing! This is a Hello Kitty Melody & Light Keychain. Made in 2001. When you press the button with Hello Kitty on the airplane, a melody plays (song title: Bear-chan's Picnic). At the same time, the propeller lights up. The battery can also be replaced. I think it's a very cute and rare keychain. It's unopened, unused, and has been stored at home. I'm also including many other retro goods!
