There are Harry Potter fans and Harry potter haters and if you really do not like Harry then you probably love Lord Voldemort instead.
If you do then now you have the option to get a real Dark Mark Tattoo to show you loyalty to Voldemort.
And yes this is a temporary tattoo so you can still change your mind if you wanted to. You can even change your mind more then once because this Dark Mark Tattoo comes in packs of 5.
