This box is made in Sweden, by Trangia, and it's as basic and ancient as anything we sell. It is as plain as an aluminum box can be, and is still the world-beater when it comes to protecting your squishable chow on commutes, campouts, and tours. Like for instance, 12-to-16oz bags of frozen berries or vegetables; or fresh ones. If you get blackberries in a plastic tub, put the tub in here. Or hard boiled eggs, or sandwiches. Put those things in this box (still in the bag if it makes sense to), and they'll stay in good shape no matter what. There's no locking mechanism & no gasket. It's just a Swedish aluminum box, and if you dent it and beat it up, you can bend it back and make it work again. We offer a double-your-lifetime warranty on it, which we believe is the best warranty in the industry. Approximate outside dimensions: 8" x 5-1/4" x 2-5/8". It weighs about 8.5 ounces, and holds enough food for one hungry person for one night.
