What is a erasable pen?
Using special ink, refined by special technology, it can be divided into erasable ball pen, erasable neutral pen, erasable water pen (color is slightly lighter than water pen), erasable pen and so on. Its handwriting can be erased by ordinary eraser or special pen in a certain period of time, and can be revised repeatedly, but some pens can not be written, which has the double advantages of ballpoint pen and pencil. Its appearance, writing and cost are similar to those of ordinary ballpoint pens and neutral pens. It can be of different grades and colors, and can be widely used in writing, painting and drawing.
At present, there are two types of erasable pens on the market: high temperature achromatization and microsphere capsules. High temperature change causes color to disappear by rubbing and heating with rubber, but colour will appear at low temperature. The disadvantage is that it is not suitable for long-term preservation, and it is more inconvenient to use in winter. It takes a long time to frictional temperature to make the color disappear. Microencapsulated erasable pen uses microspheres to encapsulate pigments. The particle size of microspheres is larger than that of paper fibers. The microsphere pigments can be easily erased by erasers. Can be stored for a long time without fading!
