The material is kiln dried, surfaced on two sides and ready to use. Minor checks, incursions, and planer bite may exist in some boards. These are all well flame figured and have rich color. Rambutan is a dense and durable hardwood that takes a high natural polish! We’re sure you’ll love it! This piece of lumber has a couple penetrating bark incursions present. There is a 30" check (3/4 of the length of the board) on the back face, 2" from the edge.
