Esterbrook Model J Blackberry Ebonite Fountain Pen

The Esterbrook Model J Blackberry Ebonite is made from genuine ebonite — a hard rubber material that gives the pen a warmer, slightly flexible feel compared to acrylic, and develops a subtle patina with use. The deep blackberry color is rich and complex, and the Fine Flex nib option rewards writers who want expressive line variation from a vintage-inspired body.
