This is a cute and effective way of carrying some of your food while exercising portion control. It is compact, yet it can fit two different types of foods while sealing them away from each other - and adding a pair of chopsticks at the top (though you could fit some other utensils too.) It is all held together using a thick black elastic band. There are plenty of other bento boxes in the store that are larger or in a different shape or have different components to this one, so do not think that this is the only one there. The quality is not as great as a box from Japan, but it works fine for the price.
