Both are microwave-safe cooking utensils. This is a set of a 2-go (about 2 cups) and a 1-go (about 1 cup) rice cooker, which can also be used as a rice container, making it easy to reheat rice. The black, circular 2-go type cooks in about 12 minutes at 600W (excluding soaking and steaming time). The 3COINS KITINTO white 1-go cooker is a convenient item that cooks in about 6 minutes at 500W. Both have been used a few times. There are no noticeable scratches, but please understand that these are used items. The 1-go cooker came with a small rice paddle, but it has been lost. Each comes with a recipe and instruction manual. Black: w180/h86 White: w120/h125 The white one was purchased at 3COINS.
