This Platinum Pen’ s unique mechanism enabled a pen with a screw-type cap to offer complete airtightness using the inner cap. It provides smooth writing with fresh ink at any time. There is no need to dip the pen up to its gripping section into the ink when drawing ink using a converter. The newly- designed feeder of PROCYON fountain pen lets you draw enough ink only by dipping the nib up to its end. In this way, it made it easier to draw ink even when only a small amount of ink is left in the bottle. In 1962, Platinum Pen launched Japan’ s first fountain pen that employed a pentagon-shaped gold nib. The same production know-how for such a pen nib is also applied in the PROCYON fountain pen. Its resiliency realizes writing feel similar to that of a gold nib in spite of being made with stainless steel. Although it has a voluminous metallic body, it has achieved the best weight balance by using aluminum for the material. In addition, a close attention has been given to obtain a good balance when the cap is placed on the back of the pen so as to offer a pleasant writing experience. Coatings are used to create different textures such as matte/smooth texture or shiny texture like a pottery while maintaining the unique texture of the metallic body.
