Recommended uses: airplanes, boats, crafts, model railroad, and miniatures. Balsa cuts easily with a hobby knife, and may be stained or painted to represent any wood type. Midwest's Balsa is carefully dried in special kilns, reducing the water content to leave a light wood with a high strength to weight ratio.
