The Panther is one of our oldest designs and one of our rarest productions. Only a few times a year do we produce any. This one is in classic F-C black with a green diamondcast band, first seen in 2020.
The 40 Panther is a long capped pen - 5.5" when capped. There is a center taper in the barrel, so the length is only 6.5" (to the nib tip) when the cap is posted on the barrel. The cap diameter is 5/8".
The barrel diameter is 9/16" at the thickest point and tapers down to 15/32" at the smallest.
