Jade isn't the rarest color in the modern Parker Duofold line, but it was only made from 1996 through 2001 and was not a big seller. Our jade Parker Duofold International is the more slender version of the pen and was made in the 2nd quarter of 1996, the first year of this design. Our preowned pen is in like-new condition with minimal, if any, wear. When we dipped its two-tone 18k gold nib, it wrote a very nice fine line on what we felt was the dry side. A Parker converter is included with the pen. 13.1cm capped.
