I use a Five Year diary called 'Some Lines A Day', very thin paper (rubbish really) but I've got it for a while now, and it bleeds through with most inks; even if it doesn't, even if I use a Fine or Very Fine nib, when you turn the page every word shows through (shadowing), making it messy to write on top of. I needed a lighter Black, and one that didn't soak into the paper, THIS IS IT!If you don't mind a shading Black which can look like the ink is running out on a long stroke with a fine nib, then I would recommend this ink. Drying time is slow, but that is the trade off you see, it doesn't soak through (Bleed), and it has to be lighter than X-Feather so it doesn't show through (Shadow). I just sandwich a sheet a blotting paper after my entry and it becomes a bookmark as well. (or wait 21 seconds before turning the page) See graphic. It is also Lubricated which help the finer nibs glide, and is water resistant, making it perfect for addressing envelopes which are usually budget paper and exposed to rainy days.

Maybe I got a bad batch, but this black ink does not behave well in most of my pens.

Just black really freaking black ⚫️

As solid black as black can be.

I've wanted a fountain pen that can handle permanent ink, and thus is it! Well designed. Easy to fill. Easy to clean. Great price!

The ink was fine. The Noodler's Triple Tail was a bit more wet than I was expecting, hence I returned it. Very good experience overall.

I use this ink with a Sailor Profit 21 in fine [****] But it's actually a medium nib. The ink is consistent when writing. Even though this dries for 30 seconds I tested a paper that's been dry for a few days. I put water on the paper and the ink did not run. The paper towel was to wipe the water off paper and only through abrasion only a little bit left smudge marks on the paper but were very readable. I still think this is a great ink that shows some excellent resistance to tampering.

another great experience

This ink turned me back on to Noodler's after my unfortunate experience with american aristocracy. Relatively quick drying, incredibly permanent, and lubricated, this ink is a joy to write with. The only problem with it is its not nearly as black as I would like.Regarding permanence, I have a piece of paper out in the bucket I use to douse charcoal in (don't ask). It is still legible several days after the original tossing in there and I may have to burn it because it contains several copies of my signature.

I like this Ink very much. Just started using fountain pens again after many years. I will probably try it in som technical pens as well and see if it resists clogging those nibs. This ink flows very nicely, no problems experienced with this ink and it is waterproof after it drys.

Excellent ink. It writes wet, is very black, and helps keep my pistons lubricated. It does require a bit of extra elbow grease to clean, but that is a small price to pay for the permanence of the ink. Otherwise, it's a Noodler's ink. What else could one expect?

This is a great permanent ink annnd ITS NOT PIGMENTED! You can't beat it. I think I'll be ordering another within 7 months. It flowed in my C.H. 912 and custom 74, but gave a little significance in performance in my next door neighbors 823. Says it's a new pen; I wrote with it she had Iro- Take sumi, it was butter; gave my neighbor a third of my black eel ink, she flushed, cleaned, and primed it and says it's giving actual feed back(literally) [ I stand behind a statement made by a fellow pilot fan they don't give much feedback] I tried it well what do you know, it had some feedback to express. Maybe because the reservoir systems are different or nib size.... a great mystery I can't solve cause I don't have one. To the team: if you have pilots and also have the 823 in particular and you have noodles black or black eel, please let me know. Field testing is strongly encouraged! That's a real mystery.OVERALL,Noodles Black/(Eel) are THEE BEST PERMANENT black inks highly recommended! Period!

I was honestly very disappointed in the color of this ink and the only reason that it is getting three stars instead of two is simply because it writes decently in the pens that I have tried it in so far. My issue is the color and I expected it to be slightly lighter than the other Noodler's Inks (Black, Heart of Darkness) but I was not expecting it to be so drastically light, I would put the shade to be similar to a white board marker that is almost out of ink but still legible. It is definitely grey, nowhere close to being what I would consider black. It is lighter than all other blacks that I have ever tried (Pilot, Parker, Lamy, Platinum, other Noodler's). Please don't get me wrong I love Noodler's inks but one was extremely disappointing. In case you are wondering yes I tried it in several pens on various grades of paper, and it wrote great, just very light. It actually goes on very dark and drastically fades into a light color. I also made sure the bottle was mixed thoroughly in case it was a case of the ink separating or settling and it didn't help at all. I know it is possible that I just got a bad bottle but from my experience the color was nothing like the color examples shown on this (or any other website). I will continue to use and purchase Noodler's inks just not this color.

I inherited a 1946 model Parker 51. Filled her up and the ink writes beautifully. I'm new to this, but I feel like I picked a winner

I chose it because I'm using it with a Japanese EF nib for detailed fine lines and stippling with water color wash over it. The ink is lubricated and permanent so it flows nicely with an EF nib and I can do wash over it. The only reason I gave it 4 stars instead of 5 is it wasn't quite as dark as I would have liked (maybe because of the lubricant or other technical limitation, IDK) but really its an excellent ink I would not hesitate to recommend or purchase again.

This was my first ink by Noodler's, and grant it I did not know at the time that bulletproof black would have been a better option for a new fountain pen user, but the ink just was not black but more of a grey with hues of black. I might have gotten an odd batch, but the ink is not very dark at all. It does flow nicely and the dry time is not bad at all.

If you are a fast writing, page turning note taker, this will dry too slowly for you. The dots of the iiis and the ... periods take the longest time to dry. I have had dry times of well over a minute. The Black Eel is good and well behaved if you have the time or a blotter. I have used this Eel on Clairefontaine, Rhodia, Maruman Mnemosyne, and Black n' Red papers. They all share the same dry time. I have since moved on to the DeAtramentis black Archive Ink; a very fast drying ink!

So far, am loving this ink...... have been using fountain pens for 20 years and never knew it could be so easy

Very happy with my Noodler's Black Eel ink. Goulet Co. sent my order out promptly. Thank you!

I bought the black eel ink to draw with for use in watercolor pictures. I'm still testing the ink on various papers and getting used to the flex tip in my Noodler's Ahab pen. This will be a game changer for my art and personal writing. I'm very happy and will purchase other colors soon!

I loved ordering from this company recently. The service is fast and personal and the pens I got are all beautiful. This ink should be a nice complement to smooth and elegant writing bur I haven't tried it yet because the pen will be under the tree next week :)

I use this ink more than any other. It seems to flow well through all of my pens, and yields a permanent record on documents after it dries.

To preface this review, let me say that this is my first Noodler's ink (and Lamy pen) purchase, as I'm new to the fountain pen community, so take my opinion with a grain of salt. So far, it's decent. I'm using it in a Lamy Safari EF for journaling and planning in a Travelers NB.. writing on Midori Diary paper. It writes well in the Lamy, but I've had a few times where it dryed up while writing. After a little shake and scribble, it would come back. So I don't know if that's the ink or the feed, because generally it writes smooth and wettish, which on the Midori, it doesn't dry as fast as I'd like, but that's writing a quick note then closing the book. I get smudges. Eventually I'll try a different ink in the Lamy, and try the Noodler's in my other pens to see how they behave. The value is so high though, when I heard that Noodler's fills the bottle to the brim, that's no lie.. I'll have this ink for years I think and other than the intermittent feeding issue, I really like this simple no frills black ink. The wetness I think is in a sweet spot for letter writing, but just not in the manner in how I'm using it.

I am new to inks, but so far I like the opacity of this ink. Seems to flow well and dries in a timely manner.

I am extremely happy with the quality and quantity of ink for the price. The ink dries quickly and is a beautiful rich black tone. A great day-to-day ink.

Great writing instrument!Traditional and prestigious appearance. I purchased this medium point pen from Goulet pens without a trial and it met my expectations The website and videos were exceptionally informative. The customer reviews reinforced my decision. I spoke to the staff and they were kind enough to test the pen to confirm it was in perfect working order before it was shipped. They guided me though my choice of ink (Noodler's Black Eel) to facilitate the best feel for the Visconti. Working with Jessica in customer service was helpful and I did not have any trepidation relying on Goulet Pens for a purchase at this price point. I recommend giving Goulet Pens a serious look if you have an interest in a fountain pen purchase and want to familiarize yourself with these writing instruments!!

I have become a huge fan of Noodlers. Black Eel is awesome with great flow in a 1930's Watermans with mild flex nib. I like using black, blue and blue black inks in my vintage pens, but I think they also used red and green back then as well.

So far so good� I like the color

Flows well in all my nibs. Haven't checked how water proof it is, but tough to get the ink tatoo's off. Very happy and would recommend.
