I got this to use in my Sailor HighAce Neo and it does not show through Moleskine Cahier paper at all. I have used this ink on a variety of papers and it does not feather on any of them. I've noticed some inconsistency in ink flow (sometimes light, sometimes dark) but I chalk that up to using such a fine nib. For no feathering and and no show-through it is definitely great stuff - and I love the color.

This is a beautiful, classic-looking blue-black ink that is permanent, and flows well. I use it in the inexpensive Sailor HighAce Neo fountain pen, which is also sold by JetPens, and the it writes like a million bucks. It's a terrific combination!

Both my wife and I use these. She has a 1911 regular with a ZOOM nib and I have a 1911 large with a Naginata Togi nib. These cartridges are perfect for these pens. The color is not quite blue black, more like a deep ocean blue and the ink flow could not be better. In addition, this is permanent ink -- more like pigment than dye, so when it goes on, its on. They are pricier than the regular blue black, but I like this color.
