Mono Master Nissin Chicken Ramen Cooker with Lid Size (approx.): Diameter 16 x Depth 4.5cm Capacity (approx.): 780mL Material: Stainless steel It can be used as a pot or bowl, and because it's made of stainless steel, it's lightweight, hygienic, and durable. It can be used for a long time. It has a steam vent, which is convenient. I've used it once to cook Chicken Ramen indoors. I washed it afterwards and have been storing it.
