Fake-mould anti-theft lunch box

Stop office fridge thieves with a lunch box that looks like a mouldy lab sample

Every shared office fridge has a lunch thief. This box defends your sandwich by looking like the last thing anyone wants to open: its sides are covered in raised, blotchy spots like a fuzzy patch of mould, and the lid says LAB SAMPLE 7. Thieves move on to the next box. Inside, it is a perfectly clean, ordinary lunch box with a deep slip-on lid.
