Board with grain on both sides, knot-free Please note that there may be errors of a few millimeters, and the angles may not be perfectly right angles. This is natural Japanese cypress grown in the Kiso Valley, which spans Nagano and Gifu prefectures. It grows slowly in an environment with heavy rainfall and deep snow, resulting in very fine and beautiful grain. It is famous as one of Japan's three most beautiful forests and is used in famous buildings. Over time, the board may experience discoloration such as knife marks, scratches, and blackening due to use. Wood absorbs and releases moisture through its humidity control function, which may cause warping or cracking. Please read the attached precautions to help the board last longer. We recommend washing it thoroughly with water as soon as it arrives. Please note that as a natural product, there may be cracks, warping, and minor scratches over time. We appreciate your understanding. #CuttingBoard
