This is a set of two steamers, one large and one small. The small one is about the size that can fit a large nikuman (steamed bun). The large one is about the size that can fit two potatoes. Instructions and box are not included. They can also be sold separately. We will use recycled cardboard boxes for shipping. These are steamers from Morii Co., Ltd. They are microwave steamers with bamboo charcoal.
