I believe it's unused, but there's no box. This is the price for one. There are small and medium sizes. Sizes are 11.5 x 6 / 10.5 x 5.5 cm. Green and gold. Honestly, it's a rice bowl that doesn't look very appetizing. It might be better to use it as a small bowl. Not microwave safe. Thick and heavy. Set of 4: 3600 yen. (Unclear - possibly "room temperature" or a brand name)
