Parker DUOFOLD Centennial Fountain Pen, Fine Nib I usually use a fine nib in the Red CT, so I was planning to buy a medium nib, but I accidentally purchased a fine nib, so I am listing it for sale. It is in new, unused condition, and the accessories are the warranty card, two cartridges, a converter, and the box.
