Found these at my grandmother's house. There are 5 fan-shaped small bowls and 1 round small bowl, which can be perfectly set on a round tray. You can attach silicone parts to the back of the tray with screws, and the tray will spin around☺︎ They have been stored at home for a long time, so the marks from the cellophane tape that held the base screws in place could not be removed. (See photo 4) Please consider this, understanding that they are old items☺︎
