I am new to my obsession of all things fountain pens, but I have had a chance to sample this ink and I must say, IT IS JUST GLORIOUS! I love it.

Ink sample - Fire and Ice

I love it! It is the most awesome color. I use it in my Twsbi Diamond 580 with a stub nib; it's breathtaking. It's really nice to be able to try out the different inks before one purchases a large amount of the product. I will definitely buy more of Fire & Ice!

New favorite!

I'm fairly new to fountain pens & only recently started experimenting with inks, so I've been sampling a bunch. This one went into my current favorite pen (Monteverde Innova Formula M, if just for the textures on the barrel) and immediately also became my favorite color to write in! It's very saturated and the color is light without feeling washed out. The red doesn't seem to show up well on any paper I've tried, but I also use the Fire & Ice in a pen with an extra fine nib, so there isn't a whole lot of opportunity to really show off the deeper color. I love the base blue/teal color of this ink so much, though, that it makes up for the lack of the sheen for me. This is the first ink I've tried that makes me want a full bottle.

FAQ about Ink Samples

How do I fill my fountain pen from an ink sample vial? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the fountain pen's filling mechanism.

Check out our blog post on How to Fill a Fountain Pen from an Ink Sample Vial.

How much writing can I do with 2ml of ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It really depends on how big or small you write, and the nib size you’re using. We find that usually you can get 2 good fills for a typical converter with our Ink samples, or one good fill with a piston-filling pen. How much writing depends on you more than anything else, so we recommend experimenting with different nib sizes to find what works best for you. 

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.
