It is a real vibrant blue color. I love writing with it. The name deep ocean blue is just right for it. If you like vibrant color's this blue is just the one.
I filled this ink in my dear old Parker Duofold (medium). The ink flows great, even in this wet writing parker with medium nib their is no real trouble on Moleskine paper. Only the dots are bleeding through. I tried it in a Lamy Safari (medium and fine) with no bleedthrough as result.
If you can't read my handwriting here's the translation.
I just filled my Parker Duofold (medium) with Iroshizuku kon-peki.
My Parker Duofold is the broadest and wettest writer I have. Their is a little bit of feathering and slightly bleedtrough on this Moleskine paper. The ink has a little shading wich is nice.
The color is rich and vibrant, light blue. Deep ocean blue. A nice happy color :-)
$ 0,45/ml that is expensive. With a Lamy Safari no bleed-through.

I tried this ink in 5 different Moleskines with the Parker Duofold (medium) and Lamy Safari (fine and medium) In one Moleskine their was some severe bleedthrough with the Parker Duofold (medium). So if you want to be on the safe side use this ink in a fine nib fountainpen.
