How to ensure that the ink of erasable highlighters does not accidentally spill or leak during use?

When using erasable highlighters, in order to ensure that the ink does not accidentally spill or leak, you can follow the following steps and precautions:
Preparation for initially use or after not using for a long time: When you use an erasable highlighter for the initially time or after not using it for a long time, it is very important to ensure that the ink is well mixed in the refill. First, gently shake the pen body several times, which helps to activate the ink and evenly distribute it in the refill. Next, point the tip of the pen on a table or other hard surface, press down gently, and squeeze it back and forth several times like a spring. This step helps to squeeze the ink out of the refill until you see the ink seeping out of the pen tip. If the ink still does not seep out after pressing several times, you can try to gently unscrew the back cap of the pen and then press down again a few times to promote the flow of ink.
Proper pen holding posture: The pen holding posture is crucial to avoid ink spilling. Please make sure that you hold the pen in the correct posture and avoid excessive force or improper holding method. A comfortable pen holding posture should enable your fingers to easily control the pen body while avoiding excessive pressure on the pen tip. This not only improves the comfort of writing, but also effectively prevents ink from overflowing.
Avoid pressure on the pen tip: When the erasable highlighter is not in use, make sure the cap is tightly closed to protect the pen tip from external pressure. Avoid placing the pen tip down or in a hot or humid environment, as these factors may cause ink leakage. In addition, when you put the pen in a pocket or backpack, make sure the cap is tightly closed and avoid friction or collision with other objects to prevent damage to the pen tip.
Dealing with pen tip wear: As the use time increases, the pen tip of the erasable highlighter may wear out. When the pen tip is worn and causes poor writing or ink leakage, please replace it with a new one in time. Buy a pen tip that matches your highlighter model and replace it according to the steps in the instruction manual. This not only ensures smooth writing, but also avoids the inconvenience caused by ink leakage.
Avoid excessive shaking: Although shaking the pen body helps the ink mix, excessive shaking may cause the ink to create bubbles in the pen tube, increasing the risk of leakage. Therefore, when shaking the pen body, make sure the action is gentle and moderate. If you find bubbles in the pen barrel, you can try to gently invert the pen body and tap it a few times to help the bubbles out.
Check the pen body for damage: It is very important to regularly check the pen body of the erasable highlighter for cracks or damage. These damages may cause ink leakage or affect the normal use of writing. If the pen body is found to be damaged or cracked, please stop using it immediately and buy a new highlighter for replacement. In addition, please make sure that the highlighter you purchase comes from a reliable manufacturer and sales channel to ensure its quality and safety.
Avoid using the pen as a toy: Do not give erasable highlighters to children as toys to play with. Improper use may cause safety problems such as ink leakage or accidental ingestion. Please keep the highlighter out of the reach of children and ensure that it is supervised by an adult when in use. If an accident occurs, please seek medical attention immediately and follow the doctor's advice for treatment.
