Parker Sonnet 18K Broad Stub two-tone nib unit

These Parker Sonnet Broad Stub nib units are in Mint condition, having never been used. They are 18K solid gold with a two-tone rhodium mask. They are easy to instal in Sonnet sections as they simply screw in using the threads at the end. The feeds are designed to accommodate the specific amount of ink that the nibs demand. First introduced in 1994, the Parker Sonnet fountain pen has gone through various iterations and today is mostly found with steel nibs. These nibs are from the early solid gold models and still fit into all the later pens. They tend to be semi-flexible and show line width not only by the shape of the tip but also depending on the amount of pressure applied in writing. Some consider the Parker Sonnet one of the most underrated of fountain pens.
