Manufacturers talk about the difference between gel pen, oil pen and ink pen.

Why is it called gel pen? Because the ink it uses is between water-based pen and oil-based pen, it is more durable than water-based pen and not easy to melt when it meets water, but its performance is not as stable as oil-based pen. When writing some documents that need to be saved, China oil pen is often used.

Oil pen

Why is it called oil-based pen? Because the ink it uses is oily, insoluble in water and not easy to fade and melt. Oil-based pen can write on the absorption surface and non-absorption surface, and it is not easy to be erased. When writing on white paper, there are obvious back marks on the back, which are often used where marks are needed. The advantages are high ink viscosity and long writing length, that is, more words can be written under the same ink output; The disadvantage is that the writing feel and quality are not good. Oily pens include ballpoint pens, marker pens, pigment pens and gel pens.

Water-based pen

Why is it called water-based pen? Because the ink it uses is pure water, it has a strong absorption to the ink of water-based pen when writing on paper. Water-based pens are generally used on the absorption surface, and can be erased even if they are coated on the non-absorption surface. Writing on paper generally does not have back marks. The advantages are good writing feel and good writing quality, but the disadvantages are low ink viscosity and short writing length, that is, fewer words can be written under the same ink output. Water-based pen will render when it meets water, and it will be easily cut off if it is accidentally dropped. Water-based pens include: pen, ordinary pen, gel pen, ballpoint pen, ballpoint pen, signature pen, highlighter pen, whiteboard pen and watercolor pen.
