Polyjuice flask

Certainly one of the best geeky items that you can purchase on etsy, a polyjuice flask will whisk you back to the world of Harry Potter. For those not in the know, polyjuice is a very, very powerful potion that only experienced wizards use. It allows the user to be able to assume the form of someone else which is pretty amazing if one wants to gather information or infiltrate a place. The flask is silver with a green background and the word polyjuice written on the middle. This is quite geeky because one needs to have read the books to at least know what polyjuice is and what it means.
