Friction ballpoint pens developed and manufactured by Pilot Corporation have gained a large market share as ballpoint pens that can erase handwriting. Itoya has embodied the excellent features of this friction ballpoint pen as a ballpoint pen “designed to last forever as a tool.” ＜form＞ A well-honed form that pushes simplicity to the extreme. Each form from the center of the pen to the base and crown is symmetrical, and the rotating body on that line is axially shaped, it has a beautiful form when viewed from every point of view. The clip also tightens the overall form with a sharp shape that only has a thread surface without attaching curved surfaces to the corners. ＜High Quality＞ The brass pen shaft, which has been processed with high precision, is covered with a high quality half-matte and gloss paint. The refill tank part and the trunk shaft, which has been processed with high accuracy with a gap of 150 microns or less on one side, make it possible to smoothly replace friction refills that are frequently replaced with peace of mind. Furthermore, the clip is also made of metal, making it highly durable. ＜High Usability＞ Designed to have a shaft diameter that is easy for both men and women to hold and an ideal center of gravity balance. The gap between the inner diameter of the base and the refill tip is 25 microns or less on one side. Rattling is suppressing through high-precision processing. In combination with a brass coaxial base, which has high rigidity, it has high usability, enabling users to write as intended. included: dedicated eraser Ball Diameter: 0.5 mm Ink Color: Black Specifications: 0.5 mm ball color: black Accessory: Exclusive eraser Quantity statement: 1 bottle Refill: Pilot Friction Ink Ball Pen Refill 0.5 mm (49025054083281) Ingredients/Amount: Brass To request a return or exchange, please note that it is mandatory to provide a video of the unpacking of the package.
