Bento boxes is the Japanese name that is given to these boxes to serve lunches. We have three types of them. This one is for kids, where we prepare the food. There's bento boxes for adults where we put some sushi rolls, pickles, fresh fruits, steamed vegetables, brown rice, and (?) on top. This box is more impressive. It's more for formal lunches, and it's served at restaurants or in houses.
The great thing about these boxes is that we use leftovers from the night before. We don't have to pay for food in fast food restaurants. Also, nothing goes into the garbage. We can clean it and reuse it.
