This bag is soft on the outside, making it pleasant to carry around. Many of the bento boxes on TOM fit well inside of it! I recommend getting the slimmer types, because it is hard to zip up the bag if the bento box is more square instead of a long rectangle. It's better to stack up than out.
The inside is lined with insulation so my food stays warm throughout the day too. I think it's a great buy.

I recommend this to anyone who has to carry around a lunch everyday and is tired of using plastic bags.
