Selection of Ink for Neutral Pens When selecting ink for neutral pens, the first consideration should be the color of the ink. Depending on different usage needs, such as office work, study, drawing, etc., select suitable colors. Additionally, the following points should be noted: 1. Ink quality: High-quality ink should be bright in color, dry quickly, and not easily smear, ensuring clear writing. Furthermore, good ink should have good stability and not easily block the pen tip. 2. Water resistance: Choose ink with good water resistance to prevent the ink from blurring when it encounters water. 3. Quick-drying property: Quick-drying ink can dry in a short time, reducing the formation of smears caused by hand contact. 4. Environmental friendliness: Choose non-toxic and harmless environmentally friendly ink, which is beneficial to protecting the health of users. II. Replacement of Ink for Neutral Pens When the ink of a neutral pen runs out, it is necessary to replace the ink promptly. Here are the steps to replace the ink: 1. Prepare tools: neutral pen, new ink, paper towel or cotton swab. 2. Check the pen tip: Ensure that the pen tip is not blocked or damaged. If there is a blockage or damage, please clean or replace the pen tip first.

3. Remove the pen core: gently rotate and pull out the pen core, taking care not to use excessive force to avoid damaging the pen core or body.

Test writing: Write lightly on the paper to check if the ink flows smoothly. 7. Storage: Store the neutral pen properly in a cool and dry place if not used for a while. III. Precautions 1. During use, try to avoid spilling ink or staining clothing. If it gets stained accidentally, please promptly use a paper towel or damp cloth to wipe it off. 2. Do not randomly discard used ink or neutral pens to avoid environmental pollution. Please sort and dispose of waste properly. 3. For users with special needs (such as writing a large amount of text or writing for a long time), it is recommended to regularly check the ink level, timely replace ink or buy spare pen cores regularly for replacement in a timely manner
