Happy with my order

I was looking for a work ink. Brian K at Goulet suggested Twsbi's Blue Black to suit my needs. This ink fit the bill well. It's a nice blue/grey shade and tends not to feather (depending on the paper). My work logbook doesn't have the best paper despite its cost of $15. The ink bleeds at the start of each line, and there's minor ghosting. The dollar store journal I use at home has no such issues. There is some slight bubbling and staining in the cartridge. This ink has become my standard choice. It drys after a few moments, has decent flow, and I love the colour. Thank you, Brian K. I'll be adding a second bottle to my next order.

TWSBI-Blue-Black Fountain Pen Ink

I really like this ink. It is a very unique blue-black. Somewhat different from other brands, since it also has a gray tinge to it. It was sent for comparison, and I was very happy that Goulet was able to match it up for me. It is also a nice flowing wet ink. Also, easy to wash off if it gets on your hands.

Love It

TWSBI Blue-Black checks the important boxes for me. 1. It's permanent/waterproof. 2. It dries quickly. Very low smear potential. 3. An EF nib writes an EF line with it. Some inks run wider and make an F or M stroke even from an EF. TBB has better manners. Bonus: some nice shading; probably not what you'd buy it for, but something to like about it.

This is honestly the best ink I've ever used

I am daily flabbergasted by the performance characteristics of this ink. It's truly flawless. There is minimal bleeding even on cheap paper; the flow is so smooth and there are almost never any skips; it's dry to the touch within seconds; there's practically no feathering whatsoever; at times there is almost an iridescent characteristic to the ink, and the subtle hue gradients that meander around the base color lend a delicious aesthetic the writing; and to top it all off, the vial is gorgeous sitting on my desk. I may never use another ink.

TWSBI Blue-Black

I tried the TWSBI blue-black because of curiosity about iron gall inks. I've since read that the iron gall content is quite modest, and that may explain why the ink performs much like my other excellent but inexpensive blue-blacks: Pelikan 4001 and Pilot. Those inks are great, and the TWSBI comes close, performing very nicely with good shading in a Pelikan 200 (B), the only pen I've used it in. The Pelikan ink leans toward the gray while Pilot is more blue--the TWSBI ink falls between the two. This is a perfectly good ink, and I love the bottle, but it won't displace my Pelikan or Pilot blue-blacks.

FAQs about Bottled Ink

Which pens can accept this ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Any of these fountain pens will work with bottled ink. Typically, as long as the pen can be filled with a converter, has a built-in filling mechanism like a piston, or can be eyedropper-filled, it can accept bottled ink.

What is shading, sheening, or shimmering ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Shading - A common (and often desired) result of a fountain pen ink pooling in certain parts of a letter when writing, so that the color and saturation of the ink appears different within a single letter or word. This characteristic cannot be achieved with ballpoint or rollerball pens and is a very appealing aspect of fountain pen use for those particularly drawn to all the pretty ink colors.

Sheen - Characteristic of a fountain pen ink where when ink pools another color can be seen on top of the ink, especially when looked at in different light angles using certain paper types. There is no way to guarantee an ink will sheen, but using a larger nib on a pen will help obtain sheening results in your writing.

Shimmering - Fountain pen ink that has small particles of glitter mixed in.

Is shimmering ink safe to use in fountain pens? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Yes! Shimmering ink is a great way to add some flare to your writing. We have found that a larger nib will showcase more shimmering particles while writing, but you can use any nib size and shimmering ink. All the ink we sell is safe for use in fountain pens.

You can learn more in our blog: How to Write with Shimmering Ink.

My ink smells funny, is it safe to use? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Generally yes! Ink does not smell good- it usually has a chemical smell, along with other scents such as sulfur, rubber, chemicals or even paint. However, as long as you’re not seeing anything floating in the ink, it should be safe to use.

It’s cold and my ink froze; is it safe to use? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Yes, frozen ink will not hurt your pen (after it’s thawed of course!) The issue with ink freezing is primarily a concern because certain glass bottles could break as the water-based ink expands, and then you’d have a mess!
