The ink is very shimmery but when I write with it, it is very dry and the shimmer is very light. This may be because I have a extra fine nib on the TWSBI.

Unlike some other shimmer inks I've tried, the Shimmertastics have never clogged my pens. I had some Red Lustre in a stub-nib pen left from last Christmas, and it still writes well. Magical Forest is my other Christmas go-to ink and it performs the same. These are great inks with a lot of shimmer.

This was a random sample and I put in a Twsbi Eco. Wow! Looks so pretty in the pen and writes smoothly and shimmers too. I enjoy it and look forward to purchasing a bottle.

Not exciting for me.

This is the worst of both worlds with shimmering inks. Either there's no glitter or the shimmer is so dominant that you can't see the green underneath. It often writes VERY dry, uncomfortably so, even in a pen that I've never suffered flow problems before. I was constantly having to floss the tines, and that only worked for a few pages. But then sometimes it would dump down so much ink that it feathered and bled through on Rhodia. It was unpleasant to write with. And impossible to clean! I didn't end up going through the converter. I flushed the feed using a bulb syringe twice with Goulet pen flush and almost a dozen times with water and still some glitter is left! And I might have to just throw away the converter all together. I simply cannot get the glitter out of it. I hate to be so negative, but this is hands-down the worst ink I've ever used. I don't understand it.

Very pretty green, it definitely lives up to its name. Difficult to flush, but I'll still be buying a bottle.

The color of this is a lovely emerald leaning towards the yellow side of things. The shimmer is subtle but present. I've tried it in a Preppy M and a Jinhao M nibs and it flows nicely from both.

The shimmer looked great . I did have to shake the pen (gently) to keep the particles mixed. Nice green. Wish I had gotten it before I did my cards!

Late review, but I really like this ink. I signed all my Christmas cards and gift tags with it last year and used Night Sky to address the envelopes. Both these colors had good shimmers of silver when dry, unlike some of the other samples I tried, including Emerald of Chivor. I used these inks in my TWSBI Diamond 580 with a 1.1 stub nib. I had no problems with clogging or cleaning the pen, and I did not dismantle it. I plan to use these inks again this Christmas. They are beautiful with a stub nib pen.

I received a sample of this in the final Ink Drop. It's a deep emerald green -- bright or dark, depending on the quality of the paper -- but with added sparkle. I don't see as much sheen as I do just a fine, mica-like glitter throughout the ink. I currently have it in a vintage 14K semi-soft nib pen with a good bit of flex, and it's behaved quite well. It hasn't gummed up the feed or nib, no hard starts, and it flows nicely without being too wet. The shimmer/glitter is subtle but reliable. I plan to use this to sign and address this year's holiday cards.
