All the differences lie in the composition of the ink: oil-based, neutral, and water-based. 3 different ink ingredients create different writing characteristics For comparison of ink composition and pen name, please refer to the following categories: **Ball pen ------ oily or neutral** **Gel pen ------ Gel pen** **Ball pen ------ water-based or neutral** At this time, everyone must have discovered a problem: **So, does "neutral" ink count as a ballpoint pen or a ballpoint pen?** …good question! Without going into so many circles and esoteric nouns, simply put, neutral ink combines the characteristics of oil-based and water-based inks, so you want to say it is a neutral ballpoint pen or a neutral ballpoint pen? Some people call it both ways. To be more "professional", just call it a gel pen! In the same way, the "medium oil" ink we are launching now is precisely because it combines the characteristics of neutral and oily inks, so let me name it "medium oil ballpoint pen"! Or, if you want to just call it a "medium oil-based pen", that's fine! **■Special description of 3 ink ingredients:** https://live.staticflickr.com/65535/52063201128_1870b284ff_o.jpg ■ The viscosity will affect the absorbency of the paper and the writing feel when writing. The current mass market particularly prefers neutral and Water-based ink with low viscosity (but this does not mean that oil-based refills are not good, the experience really varies from person to person). ■ Writing length refers to the length of a pen that can be written. Simply put, the longer the length, the more you can write.
