"Turning the envelope over, his hand trembling, Harry saw a purple wax seal bearing a coat of arms; a lion, an eagle, a badger, and a snake surrounding a large letter H."

Sealing wax is a malleable material which, after melting, quickly hardens (onto paper, parchment, ribbons and wire, and other material) forming a bond that is difficult to separate without noticeable tampering. Sealing wax is primarily used to seal envelopes or documents.

Hogwarts acceptance letters were closed with a purple wax seal bearing a large "H" and the four animals representing the four Hogwarts Houses.[1]
