This is a wooden toy I received as a bonus when I purchased a product from Hida Furniture. It has a marble inside that you can move, and it's a mystery how it got in there! The marbles collide with each other, making a clicking sound. The natural design makes it perfect for interior decoration. - Material: Wood - Color: Natural Wood (wood color) - Features: 2 marbles There are some ink marks from a pen. This is a used toy that children have played with, so please understand that it is a pre-owned item before purchasing.
