Tested & lubricated ( fountain pen specialty silicone oil + amorphous silica) Perfect gift! Dear future buyer, This piece is maintained and is ready for use, thank you! This is a beautiful extra-fine-nibbed Montblanc Meisterstück U-hooded gold nib piston pen. The next re- inking will be done by its new owner, I only tested the mechanical flow with testing ink, then flushed it fully. This pen is great for anyone looking for an out of the factory experience with a vintage Montblanc pen! The pen is not scratched, not cracked and is very shiny and clean! The pen was also tested and it flows beautifully! According to the MB catalogues, the nib is medium (M 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 cartridges! - 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 and happy treasure hunting!
