Wikipedia: Lunchables   
Lunchables is a brand of food and snacks manufactured by Kraft Heinz in Chicago, Illinois and marketed under the Oscar Mayer brand. They were initially introduced in Seattle in 1988 before being released nationally in 1989. Many Lunchables products are produced in a Garland, Texas facility, and are then distributed across the United States.
 
Wikipedia: Bento
A bento (弁当, bentō) is a single-portion take-out or home-packed meal of Japanese origin. Outside Japan, it is common in Chinese, Taiwanese and Korean cuisines, as well as in Southeast Asian cuisines where rice is the main staple food. A traditional bento may contain rice or noodles with fish or meat, often with pickled and cooked vegetables in a box.
