This is an overseas fountain pen, the FPR fountain pen. The nib is 14k gold, an ultra-flex nib. The body is acrylic. It is said that writing is possible with a width of 0.4mm to 2.5mm. It is unused. I am selling it because I will not have the opportunity to use it in the future. Although it is new and unused and in a glossy condition overall, please consider purchasing only if you understand that it is an imported product from overseas and a personal storage item. Please refrain from purchasing if you are nervous or seeking perfection. In addition, please judge the shape, color, condition, etc. from the photos. Please also see the profile section.
