Supply and demand. As the number of units remaining drops, the price goes up. This, for example, is clearly his last piece of "blanc" paper: https://www.ebay.co.uk/itm/Blanc-sheet-of-paper-04/254895244594 (or maybe it's French paper ...) :-)
The ordinary paper that consumers use throughout their everyday life such as newspapers, books, cereal boxes, etc., is primarily made of wood pulp; however, the paper should be composed of 75 percent cotton and 25 percent linen. This is what gives it its distinct look and feel. The security thread, and portrait or numberal watermarks should be already built into the paper when it is received. A 6mm wide 3-D security ribbon should be woven into the paper. Tilt the note back and forth while focusing on the blue ribbon. You will see the bells change to 100s as they move. When you tilt the note back and forth, the bells and 100s move side to side. When you tilt it side to side, they move up and down.
The sheet of paper should be large enough for multiple images, which can be cut apart later.
