Generally, items come in a gallon-size, freezer-safe zip top bag that you can fold and contort into your freezer as needed. Sometimes we get creative, though! Bags within bags within bags - all to make sure your food is ready to go when you are!
In most cases, the difference between a small and regular order simply comes down to how much food is in the bag! Each item is different (weight, volume, count, etc.), but you get the idea.
