As we all know by now, those fun-loving inksters over at the Fountain Pen Network are running a group test of all the Iroshizuku inks.
I've had a lot of fun with this ink-of-the-month comparison, and Fuyu-Gaki brings a bright note to January's gray doldrums. My test pen was a Pelikan M200 with a wonderful, tipped italic nib. I used several papers and one other ink for comparison.
Old standby Bagasse:
The bottom line is, Dr. Inkenstein likes this ink more than the Yu-Yake in a previous test (though that ink did not have any problems with flow or cleanup...just seemed too pale...).
Fuyu-Gaki is a cheerful, happy, well-behaved color. I don't think I'd go for a bottle, however, because it's fairly close to Lamy's Neon Coral, which I already have. And my ink shelf's running out of room.
