2. Anti-Theft Lunch Bags
Another idea which is very simple, totally effective and should definitely sell more than it does. Comprising simply of ordinary plastic food bags painted with images of mould and decay, you can now leave your sandwiches in the fridge at work without the office snack raider helping himself, or risk your much-coveted sausage rolls being pinched by your nearest and dearest at home. There is an obvious downside that people will probably start to whisper about your tardy hygiene after a while, but it's a small price to pay in my opinion.
