These Pelikan M605 14k solid gold rhodium-plated nib units are factory new and are easily interchangeable at home. They can fit in any M600 or M605 pen, and specifically match the trim of the M605.
Pelikan nib units are provided by us with our usual complimentary nib tuning, which adjusts optimum pressure and ink flow to your own personal preferences. They also make excellent starting points for many of our complimentary nib customizations, including such popular modifications as Flex, Stub, Cursive Italic, and Architects Point.
