When a person is taking notes in an educational or work environment, then writing pens are often the primary utensil of choice. Notes must be clear and precise, allowing for greater understanding upon review, and lending themselves to future projects. Notes written in pencil or a weaker medium tend to be more difficult to read, and have a tendency to fade over time.
Professional paperwork must be filled in exclusively with a proper writing pen. It is one of the aspects of the business world that has not been completely transferred to electronic form. Upon reviewing important documents, it is important for the recipient to see aspects like a signature -- especially in legal documents -- in either black or blue pen. This adds a personal and professional touch to the paperwork.
Writing pens are an essential for everyday emergencies. Many people choose to keep them close at hand, in a pocket or purse, in case they have to quickly jot down some information. For example, they may need to write down appointment information or fill out and sign a check or money order. You can't do most of these things with pencils or computers.
Artists and designers use writing pens within their craft consistently. Pens, with their fine tips, are suitable for drawing details and outlines. With their strong consistency, they create boldness unmatched by other implements. Artists and designers often use them for preliminary sketches, and even final pieces. Interior designers and illustrators have a tendency to use them quite often, while making large plans and intricate drawings.
