Pencils are one of the commonly used writing instruments in our daily life. Although they are frequently used, many people may not know how to properly maintain them to prolong their service life. Here are some tips to help you better maintain your pencils and make them more durable. Firstly, store them correctly. Pencils should be stored in a dry and cool place, away from direct sunlight and damp environments. Damp environments can cause the wooden part of the pencil to become deformed or even the lead to become damp and moldy. At the same time, pencils should be kept away from metal objects, oily substances, etc., to prevent scratches or dirtiness. Secondly, use them moderately. When using a pencil, avoid excessive force to prevent the lead from breaking or deforming. In addition, do not put the pencil in your pocket or backpack in friction with other hard objects to avoid scratching or damaging the barrel. Thirdly, clean them regularly. Regularly cleaning the surface of the pencil can remove dirt and traces, keeping the appearance of the pencil clean and beautiful. You can gently wipe the surface of the pencil with a soft cloth or paper towel, avoiding using too rough items that may damage the barrel. Fourthly, put on the cap after use.

After using the pencil, put on the cap in a timely manner to prevent dust and other debris from entering the lead. If you don't use the pencil for a long time, it is best to keep the lead in a pencil box or a dedicated pencil clip. Lastly, avoid excessive use or dropping. Avoid bending or twisting the pencil excessively to prevent damage to the lead. At the same time, do not randomly discard or drop the pencil to avoid unnecessary damage. These tips can help you better maintain your pencils and prolong their service life.
