I don’t know how you open your mail, but if you belong to house Gryffindor, you would use this super cool Harry Potter Gryffindor Sword Letter Opener and slice away. Though, why you couldn’t just use a spell I have no idea.
Well, you have to get enrolled into Hogwarts School of Witchcraft and Wizardry first. This letter opener includes an beautiful lion display base/holder as well. It should do nicely to open all of your correspondence from home.
It is $34.99 from Entertainment Earth.
