The Economy series folders feature pressboard panels with leatherette finished seams and edges. Pockets are non-expanding flat style intended for a handful of pieces, not large loads. In a test we are able to get 20 sheets of Kalmus sized music (40 pages - one sheet is 2 pages) into each pocket fairly easily with room for a few more. With both pockets in action that makes for 80 pages of music. Overall size is 12 x 14 inches. These are typically special ordered for you from the factory. Limited quantities in stock. Imprints are available for an extra charge and will extend delivery time. Discounts available on orders of 36 pieces or more. Shipping time for orders exceeding in-stock quantities may run 30 days or more. Made in the United States.
