This little prank box is made for people who appreciate immature humour and have no interest in pretending otherwise. On the outside it looks harmless enough, but open it up and the surprise does all the work for you. It’s great for mates, siblings, office jokers or anyone who loves a gift that gets an instant reaction. Because it’s small and cheap, it works brilliantly as a stocking filler, desk gift or extra joke tucked in with something more normal. Silly, rude and very easy to remember, it’s the sort of prank present that does not need much explanation.
