A detailed explanation isn't really required here, as this is obviously a beautiful, and thoughtful card. It just happens to have a penis and pubes that pop out upon opening.
You can chose from two pop up willy sizes, large or small. Depends on what you're into.
If you're feeling like a hairy penis inside a card isn't enough. You can add an exploding butterfly which will scare the pants off them for £2.99, some crabs in the pubes, or an always win scratch card, where your spuddy is guaranteed to win at least *a fake* £10,000+. There's special discount if you add everything!
Thank us later.
