Yakiniku Puzzle A cow-shaped puzzle with a design that reveals the internal structure. It has 37 parts. There is no base sheet. The box is torn, has scratches, and other damage. There are places reinforced with tape. I think I bought it 7 or 8 years ago. My child played with it, so there are scratches, etc. It says the color changes with temperature, but perhaps due to aging, it didn't change much. Please understand that this is a used item. Thank you.
