The Prontus is slightly lighter and smaller than the Medula but still has similar banding and filigree. The polished metal work adequately shows off the curves and features of the pen. It is still as high quality as the Medula and retains the writing prowess of a status pen.
 
The colour of this makes me think this is what a galaxy looks  like through the Hubble Telescope.
 
This pen has a velvet-coated spring-loaded metal presentation case and a tied velvet pouch.
