It is a representative ballpoint pen model of Montblanc, designed to fit in a jacket pocket. Based on the "Germany" marking, serial number, no clip engraving, and the type of mechanism, I believe this is a second-generation model manufactured from the 90s to the 00s. Using a Montblanc ballpoint pen yourself is enjoyable, but I recommend keeping one in your inner pocket for business purposes. To offer it to someone at the right moment. I personally believe that a Montblanc ballpoint pen is the only jewel that allows you to share values with others through a common experience. The high-viscosity, sticky refill makes it difficult to scribble, encouraging the user to write slowly and deliberately. In general, it can be said that this is a writing instrument that creates relationships and status. #Tamayoshi's Fun and Enjoyable Fountain Pens
