Platinum Carbon Black Ink

This ink has worked great for me so far -- very black, dries quickly without smearing, doesn't clog my fountain pen. I'm using it in a Noodler's Ahab Fountain Pen (http://www.amazon.com/gp/product/B00AWFEK72/) which lays down quite a bit of ink. Originally I was using the pen with the recommended Noodler's Bulletproof Black, but it would smear significantly if I erased over it, even days after drying. I tried this Platinum Carbon Black instead, and it's tons better -- the ink is dry and the pencil beneath is erasable very quickly. Huge improvement over the Noodler's.

For me, Platinum Carbon Black Ink is a must for beautiful invitations that must be sent out during the rainy winter months. It is very waterproof, and the ink is as black as I would ever want. It was recommended to me by someone who really knows fountain pens. The flow is excellent in my Pelikan pen. I would probably not leave this ink in the pen for a long time, but for days of invitation writing, it flows every time I pick up the pen. Amazing!

Ordered this once and the ink performed superbly. Jet black and completely waterproof. I ordered this ink once again and the ink was incredibly NOT waterproof. First of all, the boxing of the ink well was different. The initial order was in a small black box covered in japanese. The only English says Platinum Carbon Ink Black. Whereas the second bottle is half English/Japanese. After peeling off the sticker barcode on the second bottle, the product ID on the box read, INC-1200. Whereas the first box's product ID reads, INC-1500. Funny, though th sticker I tore off clearly read Platinum Carbon Black. The image in the product description matches my first purchase. So if you happen to get that one, awesome. It works great. Completely waterproof and as black as a moonless night.

This ink is amazing, THE definitive waterproof fountain ink. I use it to fill my fountain pens to draw and watercolor on top. The ink doesnt move a bit, which is exactly what I need. It's very "indian ink" black. I have heard that this clogs up pens easily, but I have yet to have this happen to me - if the pen doesn't start when I grab it, I just dip the tip in water and wipe with a rag, and this always gets it started right away.

This is great ink for sketching and adding watercolor washes over it. A friend introduced me to it a couple of years ago but I have never been able to find it in the US. You could only get it by ordering pens from Japan and then it would cost about $23.00 a bottle. So getting it through Amazon for the price I bought it was great! It is very permanent. Don't get it on clothing. Will dry quickly and does not bleed when a watercolor wash is added immediately after. Also it flows well in the pen...it does not clog.

It does seem to be among the darkest inks I've tried in my fountain pen, so using that criteria, I'd say it's among the best. Packed OK and shipped within expected timeframe.

Not many waterproof inks are designed for fountain pens. I do a lot of art using this ink in a fountain pen and sometimes add watercolor.

Excellent ink, very dark and lush. I can't tell if it's a cold or warm black, but it's black all right. It did clog up one of my fountain pens. I used this instead of the pen's proprietary ink refills, guess I shouldn't have done that. I'm not blaming this ink, tough, just mentioning as a warning, might not work with some pens.
