There is a favorite ballpoint pen, so replace it for this. The writing taste is smooth. I bought five sets, but both of them are subtle, but the entrance (length of ink) is different. It is not Japanese company's company. Are you building overseas?
A set of 1.5 is a bit large. Three set number is more appreciated. Because the axis itself also hurts. . . 2. Writing taste is good and satisfied 3. Entry eyes (ink length) of ink are slightly different for all five. In the case of Japanese products, it is disgusting if the entry eyes do not come out the same. (Are you filling in China?) ※ The other colors (black and red) were the same. Actually, I bought it for the purpose of replacing the ink of multicolor ballpoint pen, but for the multicolor ballpoint pen the length of the ink was a bit short, so it turned out that I could not use it unless it was used to some extent.
It is very smooth because it is a low viscosity type. Compared with other similar products, I think coloring is good. (Incidentally, I felt red and black were very thin.) I switched from the almost dark blue jet stream only about blue. However, it is very disappointing that there are only 0.7 mm options. Now we are exchanging the tip of the core with 0.5 mm of other companies and using it. We hope to release 0.5 mm. After that, I believe that the main body should be released in small units, even in one set of three colors of red and blue and the same color three sets. Because I used it for personal use, I could only get out of a pack of 5 replacement wicks.
