Esterbrook fanatics, click the headline for close-ups and pay special attention to the nib! YES! It is a rare "sunburst" 3550 nib! These are highly sought-after nibs. Plus, it comes in a very nice junior-sized minty green Esterbrook Dollar Pen! The vintage pen looks great with only light wear. We restored it with a new ink sac. You will write a firm, extra-fine to fine line with its osmiridium nib. A nice, shiny addition for your desk. 12cm capped.
