Note:

If the pen tip does not flow ink smoothly after the first use, it's suggested to wipe clean the tip with a piece of paper to avoid clogging. Then you can follow the manual to write normally.

Before use, please shake the marker (with the cap on) to make the writing better.

When writing the marker, please try to write at a 45-degree angle, therefore, the double-line effect will be more clear and better.
