Unwanted items from my family. I believe this is a WATERMAN Expert Essential ballpoint pen (matte black x CT). I don't have expert knowledge, so please judge based on the images. Used only for test writing. There are no noticeable scratches or stains, and I think it's a beautiful item, close to unused. I did a test write, and the ink came out. Please note that I don't know how much ink is left. Please refrain from purchasing if you are looking for a perfect new item. I would appreciate it if you could understand that this is a used item stored at home. The Expert series is a Waterman ballpoint pen with a beautiful, rounded, and elegant form. It not only writes and feels great, but it also elegantly enhances the user in any situation. SIZE: Length/142mm, Shaft diameter/13mmφ, Weight/36g Material: Brass, matte black finish Clip and Trim: Stainless steel, chrome finish
