Manufactured from sustainably sourced materials from the United States, our American Birch Plywood is suitable for a wide variety of projects, crafts and hobbies. Proudly made in the USA, our plywood features solid-wood Fir cores that boast superior fastener holding power, sanded-smooth veneers both front and back, and closed-grain wood veneers that take a finish beautifully. American Birch is graded as a BB-BB, which means both face and back veneers may or may not contain three to six small, color-matched patches on average and some light mineral streaks. Tight pin knots may be present. Inner cores are solid, single-piece veneers.
