With a bento box, you can carry the perfect lunch with you wherever you go. But selecting a bento box isn’t so easy, as there are dozens of shapes, sizes, and even the ones with multiple tiers. The typical bento box comes in either 1 or 2 tiers.

The size of the bento box can also give you a rough idea of how many calories worth of food it can hold.įor example, a small, one-tier bento box is usually 400ml-500ml in size. That roughly equates to being able to hold 400-500kcal of food that can contain.
