Perfect gift for a loved one! CLEANED, LUBRICATED (fountain pen specialty silicone oil + amorphous silica) & TESTED Dear future buyer, This piece is maintained and ready for use, thank you! This is a Montblanc Meisterstück 121 Z-hooded nib cartridge pen. The nib on this pen is also good for precision wiring since it leaves a very fine line. It's close to factory condition and it shows almost no scratches. The pen was also tested and it writes beautifully. According to the MB catalogues of the 70s, the nib is extra-fine (E-F class) and of U - hooded type. As a vintage objects collector myself, I made sure you will get a fully functional and complete piece of art, using my extensive knowledge and handling them with care, as I would do for myself. I will never give away something I wouldn't want myself, even more so since everything here is part of my own collection. Please Note: - The pen is a cartridge type, compatible with any modern day refills. - The back panel is used to provide a safe cushion for the photographing process - The shipping will be done by courier, with the best protective packaging, insurance and a tracking code, as I would do for myself Thank you. Happy holidays and happy treasure hunting!
