This is a collaboration item between Traveler's Notebook and Prada. I am selling it because I mainly use pencils. Writing has been confirmed. I believe the ballpoint pen ink has more than 90% remaining. Because it is made of brass, oxidation may have progressed from the state in which the photos were taken. Please only purchase if you are able to care for brass. The Prada collaboration ballpoint pen is quite rare and is no longer sold on any sites. I believe this is the only place to get it, so how about it? Please refrain from negotiations as I am considering keeping it as part of my collection.
