Pack a multicourse lunch of both hot and cold items in Zojirushi's Mr. Bento lunch jar. You can stack a hot soup, a cold salad, and two side dishes in each of the four bowls; all your food will keep their temperatures for up to six hours. The thermos itself is also vacuum insulated.
The smaller Ms. Bento comes with three inner containers instead of four. Both models include a carrying bag and forked spoon.
