Excellent little gadget!
Initially bought this for a work colleague who always brought his lunch in, in a tesco carrier bag every day!. He was pleased to bits with it! He does not scrimp when it comes to his sandwiches, so wouldn't agree that it's too small for a good sized sarnie. It looks fab and is certainly worth the money. It was so popular in the office that I've ordered 2 more! (Would make a great stocking filler / secret santa - worth getting now)!
If you like homemade sandwiches, and have a small bag - this is the perfect sandwich box. It fits one well filled sandwich... admittedly some oversized loaves (Warburtons Seeded Batch) need a little persuasion, but are easily convinced this is the tupperware box for them! - Until lunchtime!
Regardless of your feelings towards Marmite - this sandwich box is the perfect size. Minimal tupperware, Maximum Lunch!
