I'm SUPER happy with my first sheening ink as a fountain pen newbie. I was so surprised that all of my journals displayed the ink nicely in my TWSBI Eco. On tamoe river paper it was the most pronounced, but even my personal journal which I don't know the name brand of showed it really nicely. It dries slower than my normal waterman black for sure, but when underwriting I get no issues in my journal.

I thought this color was great. It is similar to a lot of other colors in this space, but I liked the contrast on this one just a bit more. Depending on the paper it will smear very easy, even after drying. If there is any bit of moisture on your hand days later you can still smear this on the paper. My paper sources are usually Tomoe river paper, MD paper and Leuchtturm 1917. Doesn't matter the source it will smear with any kind of moisture or higlighter. I still think the color is worth it and it shows up beautifully on cream or ivory white paper, but my preference is the ivory.

There is a red sheen to this dark blue ink. Problem is that it comes off on the fingertips of the left hand, gently holding the paper as the right hand writes and fills up the page. I am using a Conid pen with a B stub nib, writing on Rodia paper.

Perhaps I received a bad batch. Even using it on high quality paper like Rhodia or Mnemosyne, there's very little sheen. It is commonly described as a wet medium flow ink but for my bottle, the ink gushes and pools onto the paper, immediately saturating and causes feathering. For comparison, Sailor's Ripe Fig ink (with copious sheen) is supposed to be wetter, but from my experience, the Polar glow blows out like water. I understand there are lots of positive reviews for this ink, but I would return mine if I had tried it before the thirty day return period. Maybe it's a poor quality control issue by Diamine. I will try leaving the lid off for a few days to see if evaporation can help reduce the flow rate but I expect I'll be dumping this out, sadly.

Just enough sheen and shimmer with a wider nib pen

I like it but it smears even when dry if your hands are sweaty

Amazing sheen, daily driver in lamy safari with 1.1 stub

Beautiful ink, my first sheening and i love it.

I just received this ink today and immediately put it in a TWSBI Diamond 580 ALR with Stub nib. It's amazing looking. Great blue with subtle red sheen on edges. I've used it on three different brands of paper and looks good on all of them. I might make that pen dedicated to this ink it's so good.

I most often use a dip pen with this ink, and I absolutely love the sheen. The bright blue is a lovely color on its own, and then the seamless appearance of the red around the edges or where the ink pooled looks incredible. I can write a whole page with this ink and then just sweep my eyes over it to enjoy the full effect.

The ink is my first special effects ink. It's interesting to experiment. I found the better the paper the better the results. A free flowing pen and generous nib can be a added measure to benefit from the inks features. The color shift is very good and has a quality that is rewarding to the writing.

My new favorite Ink! This ink is awesome! It shimmers beautifully and makes taking notes in meetings or just writing a grocery shopping list a joy!
Life can be so dull! Treat yourself to a bottle of this ink!

That is what I would have. This ink is so different in color. Pinkish blue and it holds together real nice.
Looks great on paper! Did not disappoint!
Will buy more as long it's around!

The ink wrote well and sheened on the glossy paper as anticipated. It can be finicky to get the ink to sheen but the key I found is write slowly so puddles of ink form and those puddles will sheen beautifully. It works well and has made me satisfied. I would recommend the ink to everyone to buy. A wonderful overall ink.

I love this Diamine ink and how beautiful it looks on my Hobonichi planner.

I decided to give this ink a try. Smooth. Vibrant. And the color variance is so pretty. Very happy with this product.

Love this ink!! Put it on a broad and a stub nib and enjoyed all the colors popping!!

Good stuff

Just beautiful and you could use everyday or for special writing.

Beautiful colors and.flows well.

The color of this ink is beautiful. The contrast is fantastic. And it flows just perfectly out of the pens I tested this out of. I got an ink sample of polar glow randomly and had to have more.

This is a beautiful blue with a red sheen. I tested this on a Clairefontaine BAsic notebook and it showed well. If this color is out of stock, the Wearingeul Valley of Fear is a close match with the same effects. This bottle has more ink and is less expensive than the Wearingeul.

It works great in any size nib. My Opus 88 flex loves it, Lamy 2000 medium, Diplomat Magnum Fine—all no problems. It doesn't dry out in my pens like similar inks from other brands.

The shade of blue is amazing! The red sheen, in my experience actually comes across closer to purple than red and personally, it makes me really happy. This ink is going to be a definite daily use and regular reorder for me.

Perfect ink . Can’t stop using it . Beautiful .

Beautiful ink

This is sooooo pretty and I can't wait to really use it in January. I dip pen tested it and wrote a little with it and love the color and the sheen is so cool. It is a smooth flowing ink and seems to dry a little slower, but it is so pretty that I don't care how long it takes to dry. I like it better than OS Nitrogen. Yes, I said it.
