Although the eraser of an erasable pen is called an eraser, it is different from an ordinary pencil eraser. The eraser for erasable pens is only produced for special pens such as thermal erasable pens. The hot-erasable eraser is a special eraser for this kind of pen. When using a hot-erasable pen, this eraser works the same as an ordinary eraser. The eraser of an erasable pen is different from an ordinary eraser in that it generates heat through friction to cause the writing to disappear, so the eraser of the erasable pen will not run out.

An erasable pen is a pen with special ink that can be erased with a rubber eraser after writing.

1. There are currently two types of erasable pens on the market: high-temperature erasable pens and microsphere capsules. High-temperature erasable pens generate heat by rubbing with an eraser so that the color disappears, but the color will appear again when exposed to low temperatures. The disadvantage is that it is not suitable for long-term storage, and it is even more inconvenient to use in winter. It takes a long time to rub and heat up to make the color disappear. Microcapsule erasable pens use microspheres to wrap pigments. The particle size of the microspheres is larger than the gaps in paper fibers, and the microsphere pigments can be easily erased by the eraser. Can be stored for a long time without fading.

2. Erasable pens use special polymer materials as ink base materials and are assembled through special processes. During the writing process, the ink forms an erasable pigment film on the paper through the pen tip, and the ink can be erased. The writing can be erased with an ordinary eraser like a pencil within a few hours. The remaining writing will not fade when exposed to water and can be exposed to the sun for a long time. It does not fade and becomes indelible permanent writing after 48 hours, which can be maintained for a long time. The appearance and writing of this product are similar to other ballpoint pens, and are available in various colors such as blue, black, and red.

3. Erasable pens are a good choice for daily homework, but it is better to choose signature pens when signing important documents or taking exams. This is because the writing of erasable pens disappears when exposed to high temperatures. Under the influence of a lighter, the handwriting of the erasable pen gradually disappeared. Therefore, to be on the safe side, do not use erasable pens on important documents such as securities and signatures.
