Seashell is created using a subtle blend of white oils which are buffed into a lightly brushed surface to give the impression of a raw untreated oak. The oil is then cured under UV light to give a durable and beautiful oak floor. Tundra plank is an elegant board with a unique birch ply construction which gives it ultimate stability. TK104 Seashell Plank is available as a herringbone floor here.
