In-person grinds, tuning, and repairs of fountain pen nibs to suit you. Custom work can be done to any brand of pen that you own. Based on the previous event at Bertram’s, grinds and repairs took up the entire day so Prêt à Porter pens and nib units will not be sold on this date. The Nib Tailor tester set will be available if you are “just for fun” curious about grinds or Additive Pens… this is a great time to try with zero pressure to buy nor concern about damaging someone’s prized high-dollar pen.
