Compared with the erasable ballpoint pen, the erasable gel pen with "magic pen" has a great improvement in writing, but it does not conform to people's writing habits, and there are many restrictive factors in modification: one modification can still be modified many times, whether primary and secondary writing is needed, and whether the writing after modification with magic pen is the same as that of the main pen. How long does it take to write after you wipe it with a magic pen? These problems have been puzzling this pen, and whether it is environmentally friendly is the biggest focus. Therefore, this product featuring "Boma" has been difficult to upgrade in China! And as an exam like the college entrance examination, the education department has explicitly banned it below! Therefore, be careful when using this pen! A light-colored erasable gel pen can be erased with an eraser. To tell the truth, the key problem of this pen is that the handwriting looks laborious, which is not in line with people's habits, because the color is lighter than ordinary thermal fax, which is not suitable for scanning and difficult to popularize in the market. In addition to light color, there are pens with large water output. Ink is not dry, easy to block pens, and is not accepted by the public. Has gradually withdrawn from the market!

The erasable gel pen represented by Mitsubishi in Japan is light in color and can be erased with an eraser. Now many domestic ink manufacturers are copying. Although Japan gave up this market, it was mainly because of high profits! This kind of ink uses heat-sensitive resin pigment, which is easy to dry and writing is not smooth. Moreover, the handwriting is easy to erase with fingers, and even the friction between papers will erase the handwriting, so it has been difficult to have a big market! Moreover, in the education departments of Shanghai, Zhejiang, Jiangsu, Wuhan and other places, students have been banned from using this erasable gel pen.

Erasable gel pens that can be erased with ordinary erasers are well known. A real gel pen is used to write and save documents. How difficult it is to erase them with an ordinary eraser has always been the development direction of writing ink. Many universities, including Tsinghua University, Shanghai University and Wuhan University, are conducting this research, but because it is too difficult, there is no breakthrough yet! In April 2007, erasable gel pen ink made a new breakthrough. The newly developed erasable gel pen ink technology uses high-quality nib and special technology to make erasable gel pens, which has changed the status quo of the so-called erasable gel pens in the past: either it can be erased with a magic pen, which is inconvenient to modify, and the modification times are limited to one time, and it is not environmentally friendly; Either the writing color is too light to be suitable for normal writing; Some are even so-called pure pigment gel pens, which are easy to block the nib, writing is not smooth, and it will spread when it meets water.

Of course, this erasable gel pen and erasable ballpoint pen have poor erasability, but they can be erased with an eraser and used in various exams such as the college entrance examination, which makes this pen unique! It can reduce the psychological pressure of candidates in various exams and play a normal level! And it is an auxiliary means for students to develop good writing habits!
