While the ballpoint pen is the most widely sold writing instrument, some stores actually sell many more roller ball pens. However, the ballpoint remains a top choice for many writers and is well-suited for all writing styles and business applications. The oil-based, paste ink dries on contact. Refills write for miles and last for approximately one year. Ballpoint refills are available in a number of colors and point sizes.

The roller ball is easy to use, a hybrid system that combines the "wet ink" feel of a fountain pen with the convenience of a ballpoint. Roller ball ink dries virtually instantly, and can be used in personal correspondence and business applications.
