Enjoy a drink with a friend and have your very own guardian looking over you with these beautiful Patronus Drinking Glasses. This set of two printed glass tumblers feature a stag and a deer Patronus, both in a swirly, electric blue design on a dark background. On the back, one glass features the Hogwarts crest in the same coloured design and the other has the infamous Deathly Hallows logo. First published in 1997, J.K. Rowling's bestselling series of novels following the magical adventures of Harry Potter, Ron Weasley and Hermione Granger has since become a cultural phenomenon. A huge success in novel form, the world of witchcraft and wizardry was then given big screen treatment in 2001, launching one of the most successful blockbuster film franchises in cinema history. Harry Potter is instantly recognisable to millions of people across the world, and is hugely popular among fans of all ages. The Patronus Drinking Glasses are officially licensed Harry Potter products.
