This is the first Vacharat on a Model 33. We collaborated with the idea for a Gothic City (inspired by Edinburgh, Scotland) using the hidden barrel to articulate steps going down to a cellar underground. Vacharat included a flash of warm color with the orange showing the torch illuminating the upper stairs. The Model 33 Abditus is unique itself in design, with the barrel of the pen the "hidden secret" within the cap.
As always with Vacharat pieces, this is a one of a kind work of art. $900 starting market price.
