This is a Kabaya bonus item. The Kabaya stamp is on the back. The diameter of the screw part is about 4cm. It's an old item, so there are fine scratches if you look closely, but it's in good condition. * One has a crack in the clear cover. It's unclear what it is, but they can be connected. The screws fit together well. How about this nostalgic bonus item? Thank you for looking.
