What are the characteristics of erasable pens?
The erasable pen is made of special macromolecule material as ink base material and assembled by special technology. In the process of writing, ink forms a layer of erasable paint film on the paper through the tip of the pen, which can erase the ink marks. In a few hours, the ink marks can be erased like pencils by ordinary eraser. The remaining handwriting will not fade when exposed to water and sunshine for a long time. After 48 hours, it will become permanent handwriting that can not be erased and can be maintained for a long time. The appearance and writing of this product are similar to those of other ballpoint pens, with blue, black, red and other colors.
The font color quickly disappears at high temperature
It's a good choice to use erasable pens for homework, but it's better to use erasable pens when signing important documents or examinations. This is because the brushable handwriting will disappear at high temperatures. As shown in the right picture, the brush-erasable handwriting gradually disappears under the baking of the lighter. Therefore, for the sake of insurance, please do not use erasable pens in Securities and important documents such as signatures.
