Produced in the Golden Age of Esterbrook, the Esterbrook 358 Art and Drawing pen is one of the most popular vintage dip pen nibs for copperplate calligraphy and pointed pen work. In its heyday, the Esterbrook 358 was one of the pens Esterbrook included in the Assorted Drafting variety box, pictured here. The 358 is a soft, flexible nib with fine hairlines and medium (average) shading. This pen point provides good variation and control.
