Gorgeous sheening green teal, tree smelling ink.
I LOVE BLACKSTONE INKS, especially the ones that sheen. They flow AWESOME out of my Jinhao x450 and x750 pens with their standard medium nib. I've also created Frankenpens out of my Jinhaos by installing the titanium Zebra G in my x450s and the standard chrome nib in my x750s. For how much these Blackstone inks sheen, they work pretty well in this pen/nib set up. High maintenance, sure, but well worth it. FYI, they don't like to be stored up-side-down in this set up, especially Blue Cypress. Lying on their side, or stored right side up is perfectly fine when they're in a Zebra G nib set-up.
