The Pilot CON-70 is a high-capacity, push-button converter designed to fit many of Pilot’s larger fountain pens, including the Custom 74, Explorer, Justus 95, Kakuno, and Metal Falcon. It is also compatible with several premium Namiki series, such as the Chinkin, Nippon Art, Yukari, and Yukari Royale. Please note that Pilot has recently updated the design of the CON-70; as a result, the specific model you receive may differ slightly in appearance from older versions or stock photos.
