Important Warning for Marker Storage

Permanent Marker Pen Notice Important Usage & Storage Notes 1.Cover the cap tightly immediately after use The oil-based ink will evaporate quickly when exposed to air. Leaving the marker uncapped for a long time will cause the nib to dry out completely and the pen to stop writing. 2.Seal well during transportation & storage Always ensure the cap is fully locked before packing or storing. Loose caps during shipping lead to ink drying and product failure. 3.Proper storage environment Store markers in a cool, dry place, avoid direct sunlight and high-temperature environments, which accelerate ink volatilization. 4.How to restore slightly dry nibs If the pen is only left uncovered for a short time: Tighten the cap, place it upside down with the nib facing down for 1–2 hours, then test writing. If the nib is fully dried out from long-term uncovered exposure, the pen cannot be recovered. 5.Tips for long-term use Do not remove the cap for more than 5 minutes during writing. For intermittent labeling work, cap the pen in time after each use.
