Stasher Reusable Food Storage Bag Clear - Sandwich Bag Size 450ml 5 "Brilliant" Miss Gwillim 22 January 2019 Very handy for the freezer. No leaks - have stored soup and fruit in them. Lies flat or stands up and because they stay flat it's easy putting things back in the freezer without doing a 'jigsaw' puzzle as you have to with plastic bags. Washes and dries easily and doesn't keep the smell of the previous item. I've used the large and sandwich sizes very successfully.
