Floo-Pow was a company that was the only licenced producer of Floo Powder in Britain. Headquartered in Diagon Alley, their operations are a complete secret. They have never answered the front door, nobody knows anyone who makes it, and no shortage of Floo Powder has ever been reported. Under the company, the price of Floo Powder has remained constant for one hundred years: two Sickles a scoop.
