This is the la base natural wood cutting board by Yoko Arimoto. It has the appealing texture unique to natural wood. Size: 26cm x 26cm, thickness 2.5cm Weight: 1.1kg Material: Rubber natural wood composite Made in Japan I used it on one side only for cutting vegetables. There are many small knife marks. Please check the photos. (They are easier to see when enlarged.) The other side is unused, so you can use it as if it were new.
