Important Notes：

Direct-fill ink cartridges are designed with a safety chamber; it is normal for them not to fill completely, and this does not indicate a quality issue or a lack of ink. Do not drop, strike, or expose the pen to direct sunlight. Store it flat or with the tip pointing downward, and do not press or poke the tip forcefully.
