These Ballpoint pens are equipped with the famous Goliath giant cartridge, which contains sufficient ink for 600 pages of 8.5" X11" sheets.
Writing remains crisp and smudge-free to the very last line thanks to the tungsten-carbide rotating ball housed in a stainless steel tip. These benefits, together with the uniquely satisfying feel, is appreciated by millions of users day in day out. The light-metal body is coated with several enamel layers in classic or fancy colors.
To replace the cartridge, simply twist off the top of the pen and replace with a new one.
