Thank you for viewing. This is a Karin (Burmese Rosewood) burl with a unique wood grain and color. Due to its irregular length, please make your judgment based on the photos. The thickness is approximately 17.6mm. I think it can be used for various purposes such as pen shafts, room dividers, interior decoration, baseboards, and handicraft materials. As it is natural wood, there may be cracks, warping, pin knots, and bark inclusions.
