In the watch industry skeleton means "cut-out-mechanism". With the Visconti Skeleton you can clearly see the nib, filling piston and the exclusive Visconti double reservoir system; the small one of the front, the large one in the pen barrel. This unique filling system is powered by the Visconti patented "double reservoir power filler" which retains up to 7 times the amount of ink in most fountain pens, yet allows the traveler to travel with peace of mind while keeping the pen filled with ink. The nib is a magnificent two-tone 18Kt. gold nib. This particular pen is in brand new and unused condition, but comes without the original boxes and papers.
