A representational prop in drama is related to the drama form being representational, in simpler terms, realistic drama. Making a representational prop a realistic prop. E.G. a candle, a suitcase or a pen. Where as a presentational prop would be non-realistic E.G. a giant bug, a fairy on the shoulder etc.
What do the numbers mean? The first number is the prop diameter. The second number is the prop pitch. This is the theoretical distance that the prop would move forward if rotated one revolution. If you were to mount your prop on a shaft and submerse it in jello, you could see this in action... A 10x6 prop is 10" in diameter, and in theory, the prop will move forward 6" in one revolution. The pitch can be thought of similar to the transmission in your car. A low pitch (like on a 10x4) is like low gear on your car--lower speed, but more power. A high pitch is more like a high gear--higher speed, but it takes longer to get to top speed, and you may lose power on the verticals.

Selena does not own the wand. The wand is a prop. Prop-Masters either obtain props from the studio prop warehouse, or rent or purchase them from a prop company. When a special prop is needed, as was likely for "Alex Russo's" wand, either the prop department, model builders, or other craftsmen build them. While the program is in production, the Prop-Master inventories all of the props after every shooting, and returns them to a storage facility, often located on the soundstage, or near by. Sometimes, after production ends, select props are sold to the public in auctions. Often, however, they are either returned to the Prop House, the studio prop warehouse, or destroyed.
