Gross but effective!
Security Briefs are made from a genuine pair of men's underpants, and come complete with revolting stains.
Concealed in the front of the briefs is a secret compartment with a velcro fastener.
Inside, you can hide your money, passports, and jewellery. So imagine you're a dishonest chambermaid, looking for something to steal, a snooping partner or some other nosey parker - will you continue grubbing around once you have found these soiled and stained Y fronts?
No, me neither!
