Graphite pencils are made from graphite, a substance with a very short half-life. Graphite will only last about a week before it degrades to carbon, or carbon dust. Therefore, using a graphite pencil or pen does not affect its quality. Most are not used to the extreme, being used for casual writing. Some may even be used only occasionally. For this reason, a graphite ink ink pen needs to be very expensive.
A graphite pen is very fine and can be used for writing in very small margins, inks, and markers. It should not be used for anything else at all. These are called pen nibs.
A graphite stylus is very fine and can use the pen to draw with. It can be used to draw graphs and equations, graph papers and charts, but must not be used to write in pencil.
What is a graphite pencil case and where should I buy one?
Most graphite pencils have their case with them. To prevent accidental contact or spillages from the pencil case with the body of your pen, they must be made of plastic. The case should be made of plastic and not plastic. Paper covers and wrappers can interfere with the use of a plastic case. The plastic case should have a metal tab for easy access. Other materials can be used to protect the handle/body of the pen/pencil. For more information on plastics, see Plastics .
A paper cover should be in order on a plastic pencil, if the pencil has a plastic case. It should not be used on a metal case without a paper cover, where the pencil can be spilled onto paper. Paper covers and wrappers make it difficult to use the pencil on another pencil, or to clean it.
For writing in graphite (when the pen’s body can be cleaned), the case is important because it provides a safe, clean place to store the pen.
I have a cheap graphite pencil. How long before it becomes unusable?
Graphite is not a good pen nib material. This is why a cheap plastic pen will not last forever. Some people, however, do not care about the ink cartridge. In that case, they should use a pencil made of graphite, with enough graphite in the battery to guarantee that the pen will last a year or more. This means that they should buy a graphite pencil case, and never let it loose from its wrapper from the
