I'm not sure if this is one of those devices you didn't know you missed till it was there, or if it's something that's extremely useless. The idea is that when you're going for a wax or having a sunbed session you place the Va j-j over your *ahem* inner areas and it will keep them safe and protected.
Place it in your *area* and they say that 'your body's natural muscular tension holds it effortlessly in place'. They're disposable and come in multiple colours, but you don't really care about how pretty it looks now, do you? They're £3.98 from Body4Real, but will you be using one?
