Do you like standard, oil-based and waxy ballpoint ink? Go with the Cross ballpoint refill available in a fine, medium or broad point and black, blue or red. If you find liquid, water-based ink flows better for you, look at the Monteverde refill to fit Cross ballpoint pens. That comes in TEN ink colors! Want to change your Cross ballpoint pen into a mechanical pencil? There's even an option for that.
