As new! Internally cleaned, lubricated & TESTED Perfect gift! Dear future buyer, This piece has been fully reconditioned and is ready for use, thank you! The story of this pen begins a few years ago when one of my professors gifted it to me for my design studies and it was also one of the first in my collection. I fully disassembled it and lubricated it to its former glory from the 1960s. This is a beautiful 14K gold nib Montblanc Meisterstück 31 piston pen. This outstanding pen stands out with its special "intarsia" nib, specific to a few production years in the 1960s. The vintage pen expert Peter Unbehauen considers this model to be among the best pens ever made, given the perfect balance between flexibility and alloy stability, adding the vintage design charm! Take a look at the review here: http://youtube.com/watch?v=VVzPf-oLip8 The pen mechanism was inspected and it is propelling and intaking ink correctly, along with being esthetically complete. The piston is smooth! According to the MB catalogues of the 60s, the nib is extra fine (E-F class) and of intarsia type. Please Note: -The pen is a piston type and doesn't need cartridges! You can use any ink bottle and dip the pen in it! -The box is there to provide a safe cushion for the pen, during the photographing process. -The shipping will be done by courier, with the best protective packaging, insurance and a tracking code, as I would want for myself Thank you and happy treasure hunting!
