Thank you for viewing! (*^^*) This is an aluminum steamer. It comes with one bamboo mat. Diameter: 30cm, Height: 39cm There are some scratches and signs of use, but it should function without any problems. There is only one bamboo mat, so please either prepare another one yourself or use it as is. I think you can enjoy healthy steamed dishes. #★okanovintageshop ↑ I have other items for sale as well.
