Montblanc - 690 - Rare azure blue body - 1980's - Ballpoint pen

I am selling this Montblanc ballpoint pen ref. 690 from the 1980s. The pen has been used but is still very nice. A new ink refill has been installed. The pen writes very well (see the photos). What makes this pen special is the blue color, very rare in Montblanc pens in general.

The pen will be shipped with signature on delivery; please review the photos before making an offer.
