Jacques Herbin Fountain Pen Ink (50mL) - 1670 Anniversary - Gris Orage

This ink is a great alternative to plain black ink. I didn't think I would like the shimmer because I tend to be more minimalist/plain, but this was a nice surprise. I wanted to try a grey ink that wouldn't be too light to be practical, nor too dark so as to look very close to black.
It's a really nice dark grey with enough shading to differentiate it from black. The gold shimmer is subtle, but just enough to add nice dimension to what is typically a pretty flat colour (grey.) The photos above show a lighter shade than I see writing at home.
I highly recommend this ink if you want something practical but with a hint of something extra. Bonus that it's waterproof-ish compared to my other inks. Get a sample and try it before you commit.

Perhaps I had such a high hope on the ink, it wasn't exactly what I was expecting.
The ink was plain black ink, however the amount of glitter that was in the ink made it possible to be spotted quite fast.
The glitter didn't clog my pen at all, however, when I finished up the ink in my pen and cleaned it for a new color to use, I noticed quite some amount of glitter left in my pen even after cleaning it with pen wash. It ended up getting glitter in my other color which was weird to have golden glitter in it.
I wouldn't recommend this ink for my friends however the glitter in the ink was indeed beautiful while using.It would be a good choice if one is using this ink for long term use.

I purchased a sample of this ink and I absolutely love it. It flows well from my fine point nib and behaved well on both cheap loose leaf and higher quality journal paper. It's hard to see the gold sheen with the sample, I'm sure I'll be able to see it when filling from a full bottle (which I just came back to purchase).

I was very pleasantly surprised to find that this ink is waterproof so will give it a try in my next pen and watercolour sketch.

I've been wanting a gray ink and this one fills the bill quite nicely. The fact that it has sparkly bits is a bonus. I love it!
