Customized Multi Color Non-Toxic Rainbow Colors Scented Custom Mini Highlighter Pen

Many highlighters have bright and fluorescent colors, and will emit fluorescent colors under the night light. The most common color is yellow, and other colors include pink, blue, green, orange and purple.

In addition, there is a dry fluorescent pen, which has no felt tip, but has a special opening to stick the fluorescent strip in the pen to the document, just like a tape. This kind of fluorescent pen is not as easy to clear as the traditional one.

The fluorescent pen has fluorescent agent. When it encounters ultraviolet light (sunlight, fluorescent lamp, mercury lamp are more), it will produce fluorescent effect and emit white light, which makes the color look dazzling fluorescent. The fluorescence principle of fluorescent pen is different from that of our watch and fluorescent rod. The fluorescent rod is a radioactive reaction that occurs inside, and the radiation generated excites the phosphor around, so they can emit light at night without any ultraviolet rays. The fluorescent pen will fluoresce only when there is ultraviolet light. You can see this very clearly as long as you put the handwriting of the fluorescent pen close to the mosquito trap and the money detector.

Now there are also colorless fluorescent pens that can be hidden. There is no color after writing, and the written content can be displayed after being illuminated by the purple light behind the pen.
