Russbe Reusable Freezer Bags – Pack of 8 5 "Absolutely Brilliant" 13 November 2020 These bags are the best I’ve ever had. Yes, there is a knack to ‘locking’ them, but once mastered they are superb. They’re very strong and keep produce really well. They also stack very easily in the freezer. I have bought several packs of this size and the medium ones (I prepare and freeze vegetables and fruit in quantity), and wouldn’t hesitate to recommend them.
