In this video, I’m unboxing what might be the prettiest Platinum Curidas I’ve seen so far—the Stone Iolite (Violet). I walk you through that first “out of the box” look (because yes, this color is a moment), and then we get into the fun part: how the Curidas retractable mechanism actually works. I also show how to take it apart safely, because this pen is clever, but it’s definitely one of those designs you want to understand before you start pulling pieces apart. After the close-up tour, I ink it up with Van Dieman’s Natura Duals and do writing tests on two of my favorite papers to compare performance: Cosmo Air Snow and Tomoe River Paper. I’m paying attention to the feel, the line, and how the ink behaves on each surface, so you can get a realistic sense of what “everyday use” looks like. If you’ve been curious about retractable fountain pens—or you just love a cozy unboxing with lots of pen details—this one is a really satisfying watch, and it’s easy to see why this Curidas has quickly earned a spot in my regular rotation.
