1. Not scraping paper is only the most basic requirement. A real brand pen not only writes but also does not scratch paper. And it should be 30 degrees left and 30 degrees right. You can't scrape paper. (It is the side of the pen tip that is most difficult to polish, not the front of the pen tip), CAMALI has passed the most demanding Japanese industrial standard JIS S 6025 certification. For it, this is only the basic requirement.
2. The pen is detachable. But CAMALI's pen container is a piston extrusion technology, which is patented. It not only prevents clogging, but also ensures that the ink is full. (ink is the most troublesome thing for ordinary ink containers, and CAMALI's technology is easy to solve. )
3. The nib is optional. According to national standards, handwriting width is divided into five grades: extra fine, fine, medium, thick and extra thick. You can buy whichever you want. CAMALI series pens fully meet your requirements.
4. Finally, the price. I think CAMALI pen is the best cost-effective pen in China. Like Parker pens of the same quality and style, Camaly is only a quarter of Parker's and half of a hero. Because these brands are OEM by others, they don't make pens themselves. Kaiser made his own pen. Moreover, Wengang, Jiangxi, which is known as the "pen capital" of China, has formed a pen supply chain.
I helped you answer so many questions, because this is also my favorite pen. I know a lot about it. Ha. .
