Thank you for viewing. This is a banana keychain. There is no information about it, and the number "663" is stamped on the body. When you look through the hole on the back, you can see aquatic creatures inside. When you move the left leg (facing you) up and down, the creature inside changes. I apologize for the lack of information. Please confirm with the photos as much as possible. We would like to refrain from selling to those who are concerned about minor details, so please understand.
