A company in Perth, Australia is now offering a unique 'Tattoo by Post' service.

You can send off for their catalogue, consisting of one hundred flaps of loosely bound skin samples, decorated with over six hundred different designs. You choose the one you want, fill in an order form and send it off, along with you arm, thigh, buttock or whichever area of your body you want tattooing. They will then return the freshly tattooed body part to you within twenty-eight days.

The company also does piercings, but they suggest that if you intend to send your cock through the post, you should use registered mail.
