Take the organic goodness of Horizon milk on-the-go with Horizon Organic UHT Whole Milk Boxes. Great as a lunchbox stuffer or snack, these single-serve milk boxes offer a wholesome alternative to juice boxes. Each milk box provides many nutrients, including vitamin A, vitamin D, and 8 grams of protein. And thanks to their special packaging, these shelf-stable milk boxes lock in delicious taste without refrigeration. More than 20 years ago, we became the first company to supply organic milk nationwide--and we've remained committed to the organic movement ever since. Our USDA Certified Organic milk is made with non-GMO ingredients, from cows that are given no antibiotics, no persistent pesticides, and no added hormones.
