I guess "small" is in the eye of the beholder. There are, like 4 or 5 different companies up here that produce those. They are quite plentiful at the Wild Oats style grocery stores. "They're great for camping." "They're great for the environment." They're basically 1L or 750mL boxes, like the premade broth or soy milk boxes. Of the ones I've tried, the cheap ones are crap and the more expensive ones really aren't that bad. and they take up less space in the recycling bins.
