Gel Pen's Use Place

File -specific neutral pen

The ink used is pigment type, which is water -resistant, sun -resistant, and is not easy to fade. For example, the signing of the ledger and important documents will require the handwriting to be clear and not easy to fade. Many companies have launched the "Exam Special Pen". In fact, it also belongs to the category of "file -specific neutral pens" and must use pigment ink. However, due to the higher cost of pigment ink, most manufacturers will be replaced by dyes. Therefore, when buying such a special neutral pen, you must choose a big brand of products and pay attention to whether there is a professional logo of "pigment ink" on its products.
