TACHIKAWA pen nibs. TACHIKAWA No. 600EF, Fine These were kept at my parents' house. My father did office work, so I believe these became unnecessary with the spread of ballpoint pens. They are likely from the Showa era (1955-1975). Those with small rust spots visible (6 nibs, right side of photo 1, photo 3, photo 5) will be packed separately. However, this is a visual inspection by an amateur, so please understand that there may be oversights. Recommended for those seeking the feel of old pen nibs or those looking for vintage stationery. Please purchase if you understand that these are items stored at home for a long time. Returns are not accepted.
