This is a wooden board that was sold as part of a shelf. It was made by an artist. The metal mounting parts are missing, so I only have the unused wooden board. The entire surface is polished and has a smooth feel. It's a light wood. A different type of wood is sandwiched between the two front boards, making it a three-layer structure. Shape: Circular Condition: No noticeable scratches or stains (there are two holes on the back for mounting) Size: Diameter 20cm x Thickness 9mm (0.9cm)
