I've taken to using primarily fountain pens for all of my day-to-day writing and to carry with me everywhere. Modern fountain pens have come a long way to make them practical. I started with and Amazon Basics fountain pen. And for as inexpensive and simple as it is, the quality was quite good. Wrote pretty smoothly, and ink flow was good. So I then thought more expensive meant a better pen. I will refrain from mentioning the brand I chose, but I thought it might be a happy medium between quality and cost. Turned out, while the pen was capable of smoothness and clean lines, it required more finesse than I was willing to provide at all times while using it. This time, I bought this Scriveiner fountain pen. The difference was nothing short of mind-blowing. Effortless, silky smooth, comfortable writing. I was expecting an improvement, but honestly writing with this Scriveiner pen has turned out to be an absolute joy... not just a chore with a tool. I find any excuse I can to use it. I'm sure the novelty will wear off as I get used to the superior quality, but this pen, at least for now, bring me great joy to write with it. I've been using cartridges and have had no problems at all and the ink flow has been grand. Some day I'll venture into using the converter and a bottle of ink... but not so far. Even the look and feel of this pen, and it's quality are plain to see. Everyone should use pens like this. It would make the world a happier place.
