The Parker Sonnet fountain pen is a timeless design from an iconic manufacturer. The pen was originally intended to the "the classic Parker" - a truly timeless product. The cigar shape, arrow clip, a generously sized nib, and excellent writing performance has backed up this original intent. The pens in the top range had 18k solid gold nibs. The next price range had gold plated steel nibs. Then the bottom, most affordable range had stainless steel nibs.
This particular pen is in new old stock condition, meaning it has not been used, but does not come with the original boxes and papers. It originally came with an 18k gold nib, which has been swapped at some point with the stainless steel option shown in the photos. It was produced in 2002.
