#231 was created from engineered wood called Dymondwood ®. Made from real wood layered into solid blocks and cut on the diagonal, the pattern of this pen forms swirls of golden oak and green. The hues vary from light to dark according to the diverse features of the individual layers of wood. You can adjust the direction of the pattern by twisting the upper barrel. The hand applied lacquer finish gives a high gloss to this beautiful pen.
