Stasher Reusable Food Storage Bag Clear - Sandwich Bag Size 450ml 5 "Brilliant for sandwiches" Fiona 16 April 2019 Took these skiing to keep our sandwiches in until lunch. Being able to seal in some air kept them from being squashed in a tight bag. Seal was faultless and kept everything fresh inside. Really easy to clean and rolled up out of the way when empty. Only downside is that the opening was a bit tight. I was fine with regular bread but husband found it tricky to squeeze his larger sandwiches in. Definitely going to get different sizes.
