Ballpoint pens are the most common type of pen used today. They are durable and easy to use. There are two basic types of ballpoint pen on the market: disposable and refillable.
Disposable pens are made of plastic and you simply discard when you're finished using. Refillable pens are typically made out of metal, but once in a while you'll find one that is made of plastic. Instead of tossing the pens away when you're finished using them, you can refill the ink or replace the ink cartridge. The pens typically cost many times more than disposable pens.
Pens typically come standard filled with blue and black ink, but today you can find pens with just about any colored ink imaginable. Disposable pens come in an array or colors, and refillable pens allow the user to fill the pen with the ink of their choice. If you need to have several colors available for one project, multi-color pens are a great choice as they have several ink cartridges inside one pen. |
