Milk in bags? Welcome to Russia. Here milk is often sold in one-liter bags, which surprised me at first. To use this milk, you cut off one of the corners of the bag and pour. They even make a little pitcher thing that holds the milk bag--quite convenient. Lot of other foods (ketchup and mayonnaise, for example) also come in bags here, and actually it saves resources to use a bag instead of a big carton. Here's a picture of a bag of milk in a pitcher on my counter.
