This vintage-inspired translucent black fountain pen has a silver steel cap. It features a hooded steel nib and fills via standard international cartridge/converter (converter included, no ink) or converted to an eyedropper. The translucent barrel allows you to easily see how much ink is left in your pen.

By converting this pen to an eyedropper, you can fill the entire barrel with ink for maximum ink capacity! All you need to do is add an o-ring and a small amount of silicone grease to the threads

Pen is in great condition with no defects
