Great it arrived just when they said it would.

I am on a quest for a waterproof black, as I need that for my work. And one that works well on copy paper, as well as in the notebooks I use to track my research notes. The Bernanke Black dries crazy fast, which I love, as well as being waterproof. The ink had varied results based on the pen used and the paper written on. Since I greatly appreciated the really thorough reviews others left on here, I want to do the same. PEN: Monteverde Innova EF Nib (drier writer of my two pens)- Copy Paper: Wrote and behaved perfectly. Good saturated black, dries instantly, only the tiniest hint of feathering. Excellent Pen-to-Paper Flow.- Exceed Notebooks: Flow is a lot drier in the notebook, flow isn't as good.PEN: Hong Dian Black Forest EF Nib (from Amazon) (wetter writer of my two pens)- Copy Paper: Put down a lot more ink, has a wet flow that spreads and feathers on copy paper, as well as ghosting and bleeds through.- Exceed Notebooks: It writes much wetter with this pen, and is just awesome in notebooks. It's not quite an instant dry anymore, but is still fast. Has the best Pen-to-Paper flow of all the combinations. OVERALL NOTES: - The ink doesn't go back and forth between the papers very smoothly. Because of this, Platinum's Carbon Black will probably beat it out as my Holy Grail WP Black Ink. But this was the closest runner up from the samples I've tested so far. But the cost per milliliter compared to the PCB, I may grab a bottle specifically for when I know I'll be doing a lot of writing in just my notebook for a while.

All I have to say is Amazing. Cuddos to Nathan for this formula. It really works like in the video!!!!

This is really a marvel of drying tech. Unfortunately, the mechanism of that marvel means that it feathers noticeably even on the finest papers. On printer paper, with a fine Lamy Safari, my stroke went from ~.7mm normally to 2mm when feathering was complete! That's atrocious! I wouldn't buy a bottle of this.

I was looking for an ink I could use in conjunction with some watercolor pencils that I love sketching with... regular black is just TOO dark sometimes. This is just right... esp. in the NOODLER'S Ahab Flex pen that I love using- when it flexes, the black shades out to a cool grey color. I'll be getting a full bottle of this once the sample runs out!

It looks like lovely ink, but I was hoping it might be more waterproof... I use my pens with watercolor washes, mostly.

It's not as black as others, it smells, and it feathers on 90g Clairefontaine paper. It's the only ink I've found to do that.

Worked great for converting Preppys and a Kultur to eyedroppers, and buying it here saves a trip to a hardware store. Thanks for stocking it. This little container will be enough to last a few decades.

Love the ink and the Rhodia Webnotebook I ordered. Packing job was top notch and a lot of care was put into it. Only thing I would have prefered was a little quicker shipping. I believe it took a few days to get it shipped out. Would order again though.

decent ink, nice and green, feathers like crazy, though, even with a rather dry nib.

Dries faster than my other blacks, but not as fast as touted, even on reasonably coarse paper (laser printer paper). Seems to feather a lot.

Fair warning: test this on the paper you intend to use before you assume it will dry fast. On copy paper, inexpensive bond, and other highly absorbent papers, it does dry fairly fast, but so does almost anything. On higher quality letterhead papers, vellum or art papers like Canson Pro Layout, this ink dries about as fast as other Noodlers ink. Which is to say ridiculously slow.

Noodler's makes an extraordinary claim for this ink (dry time < 3s on quality paper). I give it 5 stars because they pull it off. The only negatives are the spreading (it makes the line thicker than other inks for the same nib). If you use to fine of a nib (e.g. a fine Platinum Preppy 0.3mm) the ink is looks grey not black. To correct this I use the ink in a Medium Preppy (0.5mm) and F/M Noodler's Piston fill.

This is the fastest drying ink I have ever seen, although not quite as fast as it seems in the video. As I gave it to a left handed friend I am not familiar enough with it to rate it. She really likes it bit this is her first fountain pen so there is nothing with which she can compare it.

I am personally very biased towards this ink. Being both left handed and an economist it is quite possibly the perfect ink for me. The ink does feather a bit on lighter papers but that is not made any easier by the fact I have this ink in a very wet pen.

This is the most smear-resistant ink I've ever used. It smears only if I deliberately rub it a fraction of a second after writing. It flows well in a left handed Lamy Safari, and I imagine that it would work even better in a more substantial pen with a higher quality nib.

Nice deep black, like the way letters look when using Pilot Plumix

I have found this to be the best ink I've tried so far for less-than-premium paper, like printer paper, post-its, and freebie trade-show notebooks.

I got this for ink my wife who was complaining about her hand being stained with ink. This ink dries so fast it is ideal for a left handed overwriter

XF nib + too much thinking = no actual ability to write. I think i works exactly as promised and I think the SO has had better results. I muse too much.

Dries in half the time compared to Noodler's Black but bleeds through inexpensive paper at work.

The Bernanke inks I've tried (Black and Blue) both feather more than I prefer, but they do dry quickly for this left-hander. This is also not as smooth on the nib as other blacks I've tried (e.g. Namiki Black, Levenger Raven Black, Private Reserve Ultra-Black fast drying). As regards color, this appears colder (bluer) than Private Reserve Ultra-Black. These are impressions from writing on a slightly warm, off-white textured paper.

What is there to say?... It has a good price, makes my pen go and dries fast. Suitable for lefties. It is also dark enough to force me to write on only one side of the page (on both my el cheapo copy paper and Staples Arc note paper). The bottle has a nice stable base but also makes a nice tink sound when deliberately knocked over by a cat. Is good. Get.

I have the NB Blue and am in the market for a solid performing true black color. Of the black samples I've tried recently, the NB Black and Lamy Black were my favorites. Both are solidly black when wet and dry as solid blacks as well. As you would expect, the the Lamy is a bit wetter than the NB Black.

This ink is everything it advertises. And it's a lovely Black.But no matter what pen and paper I use, it adds a couple of level of thickness to the nib (i.e., my EF looks like M, my F looks like B). I use F and EF because I have very small handwriting, and with this ink it all bleeds together.

For a left handed person, this is a must ink, if in a hurry. Goes down down great and drys fast.

This was my first black ink and it runs out of my pens FAST!!

It's smooth, it's wet, it's fast drying. I love it!

Bought this ink, and it flows very nice. Only problem is that it always shows through the paper for me, even Rhodia notebooks.

I very much like the color of this black, it appears very dark and even when diluted in washing it appears only as shades of gray. The ink dries very quickly as expected and also flows VERY quickly. Unless you write very quickly this ink will put down a thick, wet line even with fine nibs. If you're looking for the quick-dry as your #1 (like for a lefty) I personally think the Bernanke Blue is better behaved in terms of flow rate and because of the smaller quantity of ink your print will dry more quickly. I love the thick, wet (for a second) line it makes.

As a left handed person I found this ink to be extremely usable with a normal nib without smearing. The only con I can think of is that it isn't a bulletproof ink. But I knew that at the outset.
