Overall, the design is nice, is not noble-office-friendly, but definitely education Tough. The color areas are clearly visible and mounted on both the capsule and the shaft. So you can immediately assign capsule and shaft and detect colors very fix.
However, it could just write longer essays for example, be a bit exhausting. It has no direct grip surface, so could often have gripping times especially during busy writing.
Writes not just one hour long essays, the pen is really comfortable to hold. I would especially recommend this pack if you often something must emphasize. Then you can always quickly take up a particular color and not have to search forever.
