Great Ink, Fast Delivery

I bought this ink to be used with my two Sailor fountain pens. Love the color.

My favorite blue

Mysterious - it is a cold, steely blue that somehow feels so inviting. It is superficially similar to Penman Sapphire, to Diamine Majestic, etc, and yet it is utterly sui generis. It is dark and yet surprisingly shades prominently, but in that unusual Sailor way where you can never predict how the ink will pool. It's always lovely, though. It's my favorite blue because it's so hard to place and yet always speaks to me. A casual eye will say, just a basic professional blue. A blue-fanatic will say, This is . . . oh, wow! There are no words! Ineffable blue! The blue of the furthest reaches of the empyrean!

Bright, shading, inspiring

This is everything that your typical Sailor ink is except for being a little less water resistant than their standard colors and it doesn't sheen much. It has very rich shading properties, has a subtle, well done brightness that makes it stand out and emote at you, but without the eye-searing contrast of some other inks. It's a very pleasing, almost hypnotizing shade of pure blue that isn't as light/bright as Kon Peki, but not has heavy-handedly intense as Bleu de Minuit from Jacques Herbin. It has the characteristic good flow that I have come to expect from Sailor inks, and is similarly well-behaved. It's an extremely competently engineered ink, and one that will melt a lot of hearts on the page, IMO, and calm many angry nerves. It's the sort of homeostasis ink that sets you at ease, puts a gentle smile on your face, and calms your mind and heart. At least, until water splashes onto your work.

Nice Ink

Love the color of this ink. Flows well and I am well pleased with it. Stacks up well against my other inks.

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!

What is your return policy for bottled ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B
