I tried to get one Stasher bag in each size. I needed to transferring frozen cubes of homemade bone broth into this stand up mega bag. I wish I got two as I underestimated the sizes. I love them for freezer storage! Easy to clean, easy closure. The only thing to be aware of is not to open too wide to keep the integrity of the seal. This size I would compare to a freezer gallon to a disposable one time use zip-top bag, but better because it stands. The durability is great. I wish I got more than one.
