Erasable pens are recommended. In general, it is recommended to use an erasable pen, because it is only a child in the third grade of primary school, which is more convenient to alter and can keep the handwriting beautiful and clean. When the grade is high, the writing habits are good and the writing is fluent, then use a pen. It is refined by special ink and special technology. Can be divided into erasable ballpoint pen, erasable gel pen, erasable water-based pen (slightly lighter in color than ink pen) and erasable pen. Its handwriting can be erased with an ordinary eraser or a special pen in a certain period of time and can be revised repeatedly, but some pens can't write, which has the dual advantages of ballpoint pen and pencil. Its appearance, writing and cost are similar to those of ordinary ballpoint pens and gel pens. It can have pens of different grades and colors and can be widely used for writing, drawing and drawing. Erasable pen is a good choice for homework, but when signing important documents or exams, it is best to choose a signature pen. This is because the writing of erasable pen will disappear at high temperature. Therefore, to be on the safe side, please don't use erasable pens for valuable securities and important documents that need to be signed.
