Rollerball pens and gel pens are two different types of pens that have some differences in nib structure, ink type, writing style, etc. Here are their main differences:
Rollerball pen:Rollerball pens usually have a spherical nib with a small ball built into the nib and the tip of which is made of metal or hard material. While writing, the ball rolls and releases the ink, transferring the ink onto the paper. The nib of a rollerball pen is generally available in different sizes, such as 0.5mm、0.7mm, etc.
gel pen:The nib structure of gel pens is more complex, using capillaries, sprays, or other mechanisms to release ink from the nib. The nib of gel pens is more delicate, usually less than 10mm size is the mainstay.
Rollerball pen:The ink used in rollerball pens is generally oil-based, as the design of rollerball pens requires a steady release of ink while the nib rolls.
gel pen:The ink used in gel pens is mostly water-based. Water-based inks dry quickly, have bright colors, and are easier to clean than oil-based inks.
Rollerball pen:The writing style of the rollerball pen is relatively smooth, making it suitable for writing for long periods of time. Due to the properties of its oil-based ink, writing is easy and the ink is relatively deep.
gel pen:The gel pen may require a little force when writing due to the use of water-based ink, but its ink is relatively clear, making it suitable for occasions that require fine writing.
Rollerball pen:Ballpoint pens are widely used in office, Xi and daily writing, especially in signatures, filling in ** and other occasions.
gel pen:Gel pens are also suitable for everyday writing, but due to the clear nature of their ink, they are sometimes used in situations where finer lines are required, such as drawing and doodling.
In summary, there are some differences between rollerball pens and gel pens in terms of nib structure, ink type and writing style, and the choice of use depends on personal preference for writing feel and inkblot effect.
