No question, but that these inks are beautiful, regardless of the color you get. However, you do need to realize that the color will stay with you for a long time: they will stain the feed, and there’s a good chance the staining will be more or less permanent. Clogging is also an issue. The best advice is to shake the pen regularly, and use the ink up within a week or so. Then, when the ink has run out, give your pen a good flushing, not just with water, but with a good quality pen flush. A thorough cleaning and you should be ready for your next go around. Just don’t use it in your best/most expensive pens, because the staining and clogging issues may leave you a bit frustrated. If you can get past the minor issues, these inks are nothing short of glorious.
