Octopus Fluids Unicorn Fountain Pen Ink Review

(Jeff Abbott is a regular contributor at The Pen Addict. You can find more from Jeff online at Draft Evolution and Twitter.)

It's not often that you see the word "Unicorn" in a product name, but experience has taught me to get excited if I do see it — especially in stationery products. Unicorns are magical creatures, so the bar is high if you want to use the name in a product.

Unicorn blue from Octopus Fluids is a gorgeous medium blue ink with loads of shading, but it also has a secret magical feature that blew me away. There's gobs of pink/purple sheen that you can easily see once this ink has dried. With lots of inks that have high sheen, you need to use a large, wet nib to really get the benefit of the sheening effect. That's not the case with Unicorn. The pink/purple sheen comes through with ease in normal writing — not just large ink swatches.

I've only used a couple of inks from Octopus in the past, but my experience so far has been great. Unicorn is no exception when it comes to the basic ink behaviors. The flow is fantastic and even a bit on the wet side. The ink is nicely lubricated and glides across the page with ease. I haven't seen any feathering or bleeding, and the ink doesn't show through on the back side of the page very much either. Shockingly, even the dry time is shorter than I expected. In most cases, the ink is most dry by the 20-second mark, but certainly by 30 seconds.

As a blue ink, it's a winner. It's a deeply saturated blue that looks great on its own. The shading and sheen only add to the fantastic baseline color. I'd describe the color as a dark cobalt. There's a lovely level of shading that adds character and depth to the rich blues, and it looks great when writing with a wide or stub nib.

Once the ink dries, the pink/purple sheen starts to pop off of the page. With all sheening inks, one of the easiest ways to accentuate their effect is to move the source of light around the page so you can see all the different ways the ink and light interact. You can't see the sheen in dim light or soft indirect light, but it really comes to life when the ambient light is bright or if there is direct light hitting it. As you move around, it's easy to notice how the colors shift in the characters on the page. It really is magical, and I can't get enough of it. This effect beats out shimmer inks any day of the week (in my humble opinion).

It seems like there are so many ink makers that are worth being excited about at this point in time. It's honestly overwhelming, but that's such a good thing. Unicorn is another ink in my list of favorite inks, and I look forward to using it for my own pleasure, but also to see the responses from other people when they see the ink dance in front of their eyes like some magical creature that only exists in our collective imagination.

Octopus Unicorn is $20 for a 30ml bottle, but you can also snag a sample vial to try out first. I try to be objective and understand that not everyone likes the same things or has the same needs from their stationery and tools. That still applies here, but I'm finding it very difficult to refrain from making a universal, absolute recommendation on this ink. It's a great ink, and you should buy it if you find it in stock.

Octopus Inks Write & Draw Petrol Axolotl Ink Giveaway

Do you ever buy an ink just for the name? If so, Octopus Fluids Petrol Axolotl would be a tough one to pass up! This ink is from the Write & Draw pigmented ink lineup, meaning the ink is permanent AND you need to pay a bit more attention to your pen cleaning routine. In my experience they clean well, but this is not an ink you want to leave unused in a pen for weeks on end. Enter accordingly!

Octopus Fluids Purpur Ink Review

(Jeff Abbott is a regular contributor at The Pen Addict. You can find more from Jeff online at Draft Evolution and Twitter.)

It's getting difficult to keep up with all the new ink makers that have popped up in the past couple of years, and I'm not complaining. The latest new ink to hit my desk comes from Octopus Fluids in Germany, and it's a gorgeous purple ink with a little bit of shading and lots of personality.

Octopus Fluids Purpur is a medium purple with a little hint of red that makes it a great choice for everyday writing and doodling. This color is part of the standard line of inks that Octopus Fluids offer, and I think it's a great standard representation of purple. It's not as vibrant as some, but it's also dark enough to make it easy to use in a professional setting.

Writing with this ink is a pleasant experience. It flows easily and smoothly, and works well with all the pens I've tried it with so far. The ink doesn't feather or bleed, and it cleans up easily as well. There's a bit of shading in this ink, but it isn't extreme. In the medium cursive italic nib I've been using recently, you can see slight color variation in each stroke, but it doesn't jump out at you. Still, it does add just a touch of variation that indicates that a fountain pen was used to make the marks.

An interesting feature of this ink that I've only seen when doing swatches or making large pools of ink is that there's a reddish sheen that hangs on top of the dried ink. It looks great under the right light, but it's only easy to pick out in swatches or areas where ink has pooled significantly. Realistically, you won't see the sheen under normal writing circumstances.

Dry time for this ink does leave something to be desired, though. In my testing, the ink normally took between 20 and 40 seconds to dry to the point where it wasn't easy to smudge with light pressure. This isn't the slowest ink to dry in my testing, but it is pretty slow. Definitely something to consider if you're left handed or want to use this ink in a notebook where you plan on quickly jotting down notes and closing the book. There will be ink spots on your hands and/or opposite pages of your notebook.

Despite the dry time, I have zero complaints with this ink. I'm partial already to purple inks, and this color just makes me happy when I'm using it. It's not as bright as some of my other purple inks, but the medium hue is gorgeous and makes it easy to use in any setting while still being obviously purple.

I'm excited to explore more from Octopus Fluids because my initial exposure with this ink has been a great experience. The 30ml bottle of Purpur cost $14, so the price is fairly standard for other small-shop ink vendors. Vanness also offer a small 4ml sample vial if you want to try it out (and others while you're at it) to see if you want to commit to a larger bottle. Try out Octopus Fluids the next time you're able!
