One of the hidden assets of all Levenger True Writer fountain pens is that they have interchangeable nibs. You can easily unscrew one nib and replace it with another. So if you’d like your True Writer to write differently, or if your nib gets damaged, it’s easy and inexpensive to replace nibs.  This expertly crafted, German-engineered bi-color fountain pen nib fits any of our True Writer® Classic fountain pens (available separately). This stainless steel nib's iridium tip helps ensure a smoother write. Available in Fine, Medium or Broad. Fine: Renders a line width of approximately 0.6 mm; ideal for calculations, editing and small writing. Medium: Renders a line width of approximately 0.8 mm; perfect for most longhand writing tasks. Broad: Renders a line width of approximately 1.0 mm; favored for document signing and calligraphy.
