I want to take a bento style lunch box to work. At work, there is no staff room, there is no where to go and sit and relax. People eat at their desks, in cars, on curbs. I'm looking for a good bento lunch box I can use that is: portable size. not to garish, has a good assortment of compartments for food and protects the food as much as possible from breakage and loss. And of course have endurance and ease of use as a product. I've been looking around, but wonder if you have any tried and true products you can recommend and where you found them and for how much? Much appreciated.
