Upgrade your pen aesthetics with a two-tone gold plating & polished steel nib. This #6 Knox nib features an iridium tipped oblique double broad (O2B) tip with the Knox insignia stamp. The two-toning process is subtractive, in that each nib is fully gold plated then individually dipped into a solution to remove the gilding to expose the polished steel underneath.This nib is 100% stamped and hand finished in Germany.
