|The water erasable pen is made of special ink and refined by special techniques. It is divided into erasable ballpoint pen, erasable gel pen, erasable water pen (color is slightly lighter than water pen), and erasable pen. The writing can be cleaned with a normal eraser or a special pen for a certain period of time, and can be repeatedly modified, but some pens cannot be written, and have the double advantages of a ballpoint pen and a pencil. Its appearance, writing, and cost are similar to those of ordinary ballpoint pens and gel pens. Water-erasable pens can be used in different grades and different colors, and can be widely used for writing, drawing, and drawing.|
There are currently two types of water erasable pens on the market: high temperature achromatic and microsphere capsules. The high temperature change causes the color to disappear by rubbing heat with an eraser, but it develops color when it is cold. The disadvantage is that it is not suitable for long-term storage, and it is more inconvenient to use in winter. It takes a long time to heat up to make the color disappear. The microcapsule erasable pen is a microsphere-encapsulated pigment. The particle size of the microsphere is larger than that of the paper fiber, and the microsphere pigment can be easily erased by the eraser. Can be saved for a long time without fading!
