It's solid wood. I've forgotten, so I'm not certain, but I believe it's either walnut or black walnut. Please judge from the photos. The dark areas are water spots, so they will disappear. It's 1210 x 298 x 55 (mm). It has been planed. As it is solid wood, there may be some warping or cracking, so please understand. It's stored in a warehouse without any protection, so there are some minor scratches. Pick-up is okay at a designated location within Nagoya city. A small discount is offered for pick-up. A discount is offered for bulk purchases with other counter materials. Please read my self-introduction. If you have no requests, comments after purchase are unnecessary.
