The inner tray is missing. It's a Heisei retro toy from 20 years ago. It works perfectly fine; when you turn the screw on the back and open the lid, the music box plays, and the Ham-Hams move along with the music. As you can see in the second picture, there is some discoloration from aging. The surface is smooth, so it seems the inside is dirty. I bought it 20 years ago and stored it with care. - Brand: Hamutaro - Character: Hamtaro - Design: With an animation character figure - Function: Toy storage space - Theme: Nature and music scene - Color: Orange and green combination Thank you for looking.
