The fine straight graining and sumptuous hues of rich Walnut make the elite Reserve Collection a perfect choice for higher end homes. The exceptional quality and beauty endure as the planking develops a lustrous patina adding depth and character as the years go by. Similar in dimensions to the Estate Collection, these planks are 5/8? thick x 7-1/2? width x 20? to 86.6? random length planks with a 4mm veneer.
