Pen Refill Preservation Skills Pen refills are an indispensable part of our daily study and work. However, how to properly store pen refills to ensure their performance and extend their service life is a question worthy of attention. Here are some tips for storing pen refills: 1. Keep dry: Pen refills should be stored in a dry environment to avoid damp and humid air, which can affect the quality of the ink and the color brightness inside the pen refill. 2. Avoid direct sunlight: Strong sunlight can cause the color of the ink in the pen refill to fade or dry out too quickly, so the pen refill should be stored in a shady place. 3.
