5 Stack a Boxes Food Storage Containers 2.5L 5 "Perfect size for cupcakes or muffins!" Emma Jane Kennedy-Senie 20 November 2018 I already had the 750ml size, and bought these larger ones as I am such a fan of the smaller ones. They are a great size for organising things in the fridge and freezer. However, my favourite use is for un-iced cupcakes! They are the perfect size for 12 cupkaes (6 stacked on top of 6, with a sheet of greaseproof in between). So handy for baking in advance, or for having a stash of breakfast muffins on hand. Brilliant product, brilliant price - seriously, buy these.
