Platinum Carbon Black Ink

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.

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.

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.

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.

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 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.

This is a wonderful ink. It is very, very dark and didn't bleed at all. I used it to address the envelopes for my wedding; they turned out beautifully. This did not disappoint. If you need black ink that dries fairly quickly and gives you crisp, clean edges, buy this. You'll be happy you did!

This ink works great! It's nice and black and totally waterproof. I had my reservations about clogging, but it flows fine in my Parker 51, and it starts up without skipping even if I let my pen sit for days.
