I am crazy about ursines (see my Rilakkuma reviews for proof), and this suave polar bear is my new bestie. This bag is insulated so it keeps my salads chill until I can get them in the fridge at work. It's a good size (bento bags tend to be quite small, which are good if you are rocking a proper bento lunch, but sometimes, you want MORE FOOD), and it is a cute design.
