What conditions should be taken into account when storing Marker Pen to ensure that their ink does not dry out or deteriorate?

When storing Marker Pen, we need to pay special attention to a series of conditions to ensure the stability and durability of their ink. Marker Pen should be stored in a cool and dry environment. Both high temperature and humidity may have adverse effects on ink. High temperature will accelerate the evaporation and deterioration of ink, while humidity may cause ink condensation or corrosion of the pen tip. Therefore, it is crucial to avoid exposing Marker Pen to direct sunlight or storing them in humid environments, such as bathrooms or kitchens.
Secondly, storing away from light is also an important part of protecting marker ink. Long-term direct sunlight will not only deteriorate the ink, but may also accelerate the aging of the pen body material. Therefore, when storing Marker Pen, choose a place with weak light and little temperature change, such as the shade of a bookshelf or in a drawer.
In addition, when storing Marker Pen, you need to pay attention to the direction of the pen tip. In order to ensure that the ink is evenly distributed and prevent the ink from settling near the pen tip and causing clogging, it is recommended to store the marker tip facing up. This can effectively reduce the risk of ink drying up and ensure smooth ink flow the next time you use it. At the same time, after using the marker pen, be sure to tighten the pen cap in time. The main function of the pen cap is to prevent ink evaporation and air from entering the pen, and to maintain the stability and wetness of the ink in the pen. For marker pens that are not used for a long time, the pen cap should be kept tightly closed to reduce the possibility of ink evaporation.
In addition to the above storage conditions, choosing the right paper to use the marker pen can also indirectly protect the ink. Paper with poor water absorption and smooth surface (such as paper for marker pens, white cardboard, etc.) can reduce ink consumption and make the painting effect better. This also helps to reduce the phenomenon of rapid drying of ink caused by excessive ink absorption by the paper. Therefore, when using marker pens, try to choose the type of paper that matches the ink.
Finally, we also need to be careful to avoid mixing marker inks of different brands or types. Different brands and types of marker inks may react chemically, affecting the use effect or even clogging the pen head. Therefore, when storing and using, marker pens of different brands should be stored separately and avoid mixing inks.
