Is this popular with B&Bers? The first one I tried had me hooked - excellent ink, nice colour and very reliable. I like the fact that it flows very well as I prefer a wet line from my pens.
Favorite commercial manufacturer. Nice palette of colors, well behaved and reasonably priced.
I got their Asa Blue as one of my earlier inks. Nice enough color, but this was before I realized how non water resistant some fountain pen inks are, and started doing my own testing. Not a big deal for some people, but for me, an ink that just washes off the page 24 hours later is not acceptable, no matter how good it looks. I don't know if their other inks are like that.
