Highlighters are often used for drawing and marking. When selecting, you can fold two pieces of translucent report paper or typing paper together, write a few words on the top paper with a fluorescent pen, pay attention to the weight and cadence, and then turn it over to check. The high-quality fluorescent pen should have no color penetration on the back of the top paper, and there should be no handwriting on the next paper.

The water-based fluorescent pen is newly produced in recent years. It is used for marking. It uses thicker and lighter ink to cover key parts for marking. After marking, the blocked text is clear at a glance. The most important role is that documents marked with fluorescent pen can not be seen to have been marked when copying!
