Absolutely gorgeous color! I originally ordered Robert Oster's Smokescreen but it was out of stock -- Chris quickly reached out to me to let me know and asked if I wanted a different color (thank you so much for the excellent customer service, Chris!). I chose Robert Oster's Aqua and I am so happy with it. The color really pops and has amazing shading qualities that show off a wonderful depth to this ink. Since I am all about inks that have a a good amount of shading, I decided to put it in my Opus 88 Demonstrator with a 1.5 stub nib to highlight this. I am happy to report that the ink has a great flow and was able to keep up without any issue. Definitely one worth adding to your collection.
Thanks! Superb service.
