Oh, and to my previous comments I'd like to add: This isn't the darkest black
ink around, so I'd consider it an "everyday black" ink and not one for fine
artwork/calligraphy. (On glossy paper, it can look a little gray.) But still,
it's affordable and has a pretty bottle.
I'm fascinated by the weird bottle this ink comes in. The ink is in the top
half, which is a saucer-shaped glass bottle with a thick base so that the ink
appears to be floating above the bottom half, which is black plastic with a
spool of blotter paper inside. (There's a lot of paper in there -- the coil
fills up almost the entire bottom. The glass and plastic halves snap together,
which might be useful if you want to hide something else in there.) Because of
its sandwiched layers, the bottle is significantly wider than most other ink
50ml isn't quite as big a bottle as some other brands (such as the 80ml Diamine)
but it's a good price, it's a snazzy bottle, and hey, free strip of fuzzy paper.
I'm no fountain pen ink expert, so all I can say about the ink itself is that it
writes properly and is black. I use premium brands like Diamine when I want
exotic colors, but for plain black I like this chubby bottle.
Diamine's "Oxblood" is a very dark maroon/burgundy color. On glossy bright white
paper, it'll be an amazing nearly-dry blood color, especially if your pen is wet
enough to have it bead up nicely at the ends of strokes. On matte paper, where
colors always look darker, it'll be a reddish-black (the color of a ripe dark
It reminds me of the "Burgundy" color of the Marvy/Uchida Calligraphy markers.
It's darker than the Kuretake Zig Letter Pen CocoIro's "Bordeaux" color (which
JetPens sells as "blood red".)
I think this is the darkest red in the current Diamine range. If you want a red
that's a little more vivid, you might consider Diamine's "Maroon".
The bottle is, as expected, heavy glass with a hard plastic cap, but note that
you might not get the marbled green cap shown in the photos here -- my bottle
has a solid black cap.
This is a nice burgundy color, but it's a little too transparent to pass as real
blood -- it's got a sort of watercolor quality to it. It's very close to the
Marvy Uchida burgundy, but a little more transparent. It's roughly the same deep
red with a hint of purple as partly-dry blood (not as red as freshly-spilled
blood, not as brown as old dried blood) but not as opaque as real blood. (If
that's your thing, you might want to try using an opaque acrylic paint
The Zig pens have a bit of a brush quality to them (with a small, mostly-stiff
point) that gives a line quality similar to a Tradio/Pulaman/Fountain Pentel,
but the Zig has many more color options. The Tradio/Pulaman/Fountain Pentels go
"scratchity scratchity scratchity" when you write -- and sometimes "spit" little
droplets in a random direction. The Zig writes more quietly, and has similar
thicks and thins, but without the occasional spitty surprise. I personally
prefer writing with the Tradio/Pulaman/Fountain Pentels, because their
scratchiness grips the paper firmly and their ink is a bit darker, but I suspect
most people will prefer the Zig's predictability and wider range of colors.
