Total capacity: 560ml (240ml rice jar and two 160ml side dish containers). The rice jar is insulated like a food jar to keep the rice warm and soft for lunch. The two side dish containers aren't insulated, but go inside the insulated carry bag that you could drop a cool gel pack into for maximum food safety. Photo of a lunch packed inside is here. The side dishes can go in the microwave, but not their lids. Picked this up at Ichiban Kan in San Francisco's Japantown for US$20 (they had rose color as well -- Bay Area bento shopping guide here).
