This bamboo sketching pen has a brush attached to make it a powerful combination pen. One end is used for ink drawing and painting, the other for Sumi color or sketching. Each piece is made of a specially selected hard bamboo shaft and carefully carved by a master craftsman into a shape perfect for black-ink line drawing. The removable brush tip can be inserted into the handle for protection and storage. Designed to be used with liquid Sumi-ink.
