Yayoi is made from local Pennsylvania Walnut as the canvas for our multicolored polka dot design. All of our inlays are made in house from odds and ends around the shop, resulting in a colorful array of wood varieties. Like many of our products, Yayoi is created using reclaimed materials to minimize our global impact on the environment. Each board is finished with food grade oil. Measures 17.25 x 7.5 x 1.75"
