Carbonized Strand Woven Bamboo Plywood 4'x8'x1/2" https://www.bambooindustry.com/bamboo-plywood/plywood-12-sc.html All of our bamboo plywood comes unfinished in both a natural (light tone) and a carbonized (amber tone) and is laminated to produce two different surface grains, vertical (edge grain) and horizontal (flat grain). The vertical grain appears as 1/4" strips and the horizontal grain appears as 3/4" strips on the surface of the bamboo plywood.
