1. If the ABS Highlighters nib is dry and cannot write normally, please take the ABS Highlighters nib out, turn it around and insert it into the nib, then you can write normally. If you still can't use it, you need to replace a nib.

2. To achieve the best writing effect, please maintain a correct pen grip.

3. If the ABS Highlighters nib is worn out and becomes unusable, remove the nib and replace it with a new one.

4. After the handwriting becomes faded, press the pen tip against the green board and gently press down several times to make the water flow into the water storage area at the front of the pen.

5. After use, please cover the ABS Highlighters cap tightly to avoid affecting the use of the effect.

6. The first time you use or have not used it for a long time, please shake the pen several times, the ABS Highlighters nib against the desktop or hard plane downward lightly pressed, with the spring a back and forth squeeze, to wait for the pen water from the nib to seep out. If you press the pen water does not seep out a few times, please unscrew the ABS Highlighters back cover, and then press down a few times.
