We've shaved 10% off the weight of the nearest comparable "Black Folder" version, and trimmed the size and concert configuration width down just a bit so you're not so crowded when you're performing with too many people packed on too few risers. The back panel is one-piece construction as opposed to 3 panels stitched together. The spine is thicker and more durable, more rounded and comfortable, and with special deep grooves that allow the material to flex around the hinge. Those grooves also help to dissipate perspiration from your hand if you're performing under hot stage lights. We've put a second pencil holder on the left side, and included one of our most popular options, the clear pocket for programs, in the base model. All this comes at a price under the cost of the deluxe Black Folder. The Choralex Compact still holds A4 and US letter and common score sizes easily and has room for a ring adaptor or double cords as well. In fact, the capacity inside is wider, so we're now including a 1-inch (2.5 cm) diameter 3-ring adaptor when the ring option is chosen.
