Microwavable Oblong Food Storage Container 2.2L 5 "Best non-lockable storage I have had!" Anna 20 June 2011 Granted, little beats lockable storage boxes for liquid contents ... but these are the next best thing. They are easy to open and close and I have used them for leftover soup with little concern. Well done Lakeland. Could you not look at smaller volumes also? I have also used the bigger size for transporting muffins ... could you not consider making one that might fit a 2lb loaf cake? A note from the team Thanks for your review. I'll be sure to pass on your suggestions.
