Platinum Fountain Pen Ink - 30 cc Bottle - Red

So, English is not my first language.
Anyway, the ink is fine, waterproof, as long as I can see, what is amazing, because I'm a illustrator. Buuuttt... is not the totally black kind of ink. It's almost gray, in my opinion, which is made this lose some points.

But if you are looking for a ink to write, which doesn't make a mess with water, this ink is totally cool.

Excellent ink, very smooth. It has a beautiful and rich blue color. It may be a bit too subdued for everybody, but I think this is the best blue-black I have tried. Definitely one of my favorite inks of all time.

Superior ink.

I bought this with a bottle of Lamy and this is even better. Deep, rich color and smooth flow. Will definitely buy again.

I would like to modify my last review "It writes very smoothly and it is waterproof. "
I found it is not waterproof. But it is not easily washed away.

It writes very smoothly and it is waterproof.
Although it is not very black, it is about 80% to 90% grey.
