A unique brush originally designed for engineers who had to do very precise striping or long line work. The need was for a tool that would carry a great deal of watercolor or ink, yet apply it in a very even consistent manner. The center of the brush is made with very long hair and is surrounded by a thick body of hair that acts as the reservoir for paint. The two work as a team to act as a marvelous tool for the artist.
