I love these bags! A smidge expensive but they are good quality which is why I keep coming back for more. I use them for soups, sauces, spag bols, stews and most leftovers really. I like how they stand up (once you get a bit of the food in to weigh it down) & seal up well. They're thick so do not leak the contents when you defrost them (which I've had happen to me in the past with bog standard supermarket freezer bags grr). They have a nice large area to write on with a permanent marker. They are pretty easy to fill compared to the 500ml ones which are a bit trickier.
