Thin and smooth
Equipped with synergy chips. Juice Up has designed a nib like never before. As a result, stress-free and smooth writing, ultra-fine but smooth writing comfort, and strength against pen pressure are realized. A new ballpoint pen with a soft and smooth writing taste.
New pigment gel ink 
The characteristic of the juice series is that the color of the ink is vivid.
The new pigment gel ink, which was developed for ultra-fine juice up, has been extremely finely optimized and has excellent water resistance and light resistance.
It is ideal for writing prints because it can be written smoothly even though it is fine.
In addition to the knock-type ease of use, it features a smooth writing taste peculiar to gel ink.
Since it is extremely fine, it is also ideal for writing in small line spacing.
The abundant number of colors is also useful when you want to color-code the main points and take notes.
The color is good, so it's easy to check notebooks and memos. The
vivid color even with thin letters makes it easy to see when you check it later.
