Junk item: Montblanc fountain pen and ballpoint pen set. The fountain pen appears to be the type that uses ink, and I tried to open the back part, but I couldn't figure it out. The ballpoint pen has not been tested for writing. Therefore, I don't know if it can be used. These items were found at home, and I don't know much about them. Please consider them as junk items. For those who understand, No claims, no returns, please.
