This is the Diamine Inkvent 2024 Day 18 door:

Day 18’s ink is Diamine Vibe, a dark turquoise ink with a pink “Extreme Sheen”. This is in fact the most extreme of all the Extreme Sheen inks so far – there’s so much sheen that you can barely see the base ink colour, even with the Lamy AL Star fine nibbed fountain pen that I used to test this ink.

Tilting the Col-O-Ring swab just a little bit shows just how much magenta sheen there is: you can see the base in colour of Diamine Vibe in just the tips of certain letters and the edge of the ink swab. The rest is just glowing sheen.

Even in my Rhodia writing sample, on paper that’s relatively absorbent and with a fine nib you can see the deep magenta sheen. It’s wild to write with this ink: you put down words on the page in a gorgeous dark turquoise and watch them dry into a vibrant pink. It’s like a magic trick.

Unsurprisingly the sheen is even more extreme on original Tomoe River paper. You have to tilt the page away from the light source to even get a hint of the base ink colour of Diamine Vibe. You can see it here compared to another extreme sheen ink, Diamine Grotto.

And here’s a closer look at these two extreme sheen inks on Tomoe River paper:

I tried to get a none sheening angle of today’s bear sketch, but U was only partially successful – you don’t get the sheen but the base ink looks much darker and almost black from the view I did get. The sketch was done on Midori MD Cotton paper, and as to be expected, Diamine Vibe was a sheen machine, and it took ages for it to dry.

Here’s a look at the amount of sheen I got in this sketch:

Here’s today’s bear, Finn from Charlie Bears. I bought him in York, and he’s cute but unnumbered.

I love the base colour of Diamine Vibe and the extreme sheen on it is WILD. I may find myself buying a full bottle of this ink just for the magical colour changing effect when the ink dries and sheen emerges. Is it practical? No. It takes forever to dry and I wouldn’t let it anywhere near my vintage pens. Is it holiday themed? Not really. But in the end, who cares – Diamine Vibe is a seriously cool ink with a big wow effect that is really fun.

Isn’t that something to celebrate?
