Did you know that Sirius Black has used this black envelope before? Instead of those Harry Potter mailers that scream in your face, he found this envelope to be more productive. The massive size along with its strength reminded him so much of Hagrid that he had to get it. J.K. Rowling doesn't like to talk about this because it kind of diminishes the power of magic, but once Voldemort tried to use the killing curse on Sirius and Sirius didn't die because of this envelope. It was so strong that it shielded him from Voldemort's powers. (Of course he didn't have this envelope later on when he does die, but that's another story - the fifth book to be exact).
Black Tyvek® Envelopes are water-resistant, tear-proof and lightweight. So flying on that brook will be easy even with this envelope under your arm. They have a peel and seal adhesive on the short side of the envelope that guarantees fast closure for those quick breakaways during that Quidditch match.
