All signs are made using the natural material of wood – three-quarter inch birch plywood to be exact. Due to the use of this material, no product will be alike due to differences in grain and the way that each piece of wood absorbs the color. Some signs are lighter or darker than the images shown. Although we strive to create a product as close to what you see; the final product may vary to what is shown on this website. We strive to use the highest grade wood available, but we cannot guarantee that any of our signs will be completely flat or without flaws. In addition, we cannot guarantee that any of our signs will not warp over time or become discolored, especially if the signs are exposed to the elements.
