Not suitable for all fountain pens, as the metal particles will sink to the lowest part of the pen's converter if the pen isn't shaken appropriately. Other than that, the ink is great! Read more

Really nice stuff! Shows itself best on really good, fountain pen-specific papers, but works fairly well with visible shimmer on more workaday paper from Walmart as well. My bottle had a fair amount of shimmer in it, more than I care for, but I either 1) shake the bottle until only some of the particles enter the suspension (still some on the bottom)-- or 2) shake the whole thing, fill the pen, return about half the ink and wait fifteen seconds, then fill with clearer ink on top after some particulate settles.

I can just play with the bottle as I love the color so much. Performs best in wet larger nibs, clearly not a shocker. These Herbin inks Ive been a fan of and I dont care to use shimmer inks for the maintenance diligence you should use. When you write with it I almost always want an ink splotch to show how great this ink is. I have not used it on a variety of paper types. Regular paper, postit, Maruman and Kokuyo currently are the notebooks in use. Read more

I absolutely love this ink. I have been using it in my medium nib twsby eco, and it is just lovely. Great sheen, smooth writing, gorgeous color. Read more
