I received an email several months ago from Hippo Noto (makers of the Hippo Noto Notebooks) about a collaboration with Kiwi Inks. The photos showed a sheeny, shimmery, purple-pink-green-blue ink that immediately ushered an audible "Wow!" from my lips. I ordered a bottle, but I didn't open it until this week.
What a wondrous unicorn ink this is! It isn't something you'd want to use in a sober office environment. Nope. This is an ink that says, "Hey y'all! Wahooooo! Let's party and eat cotton candy and ride carousels and chew grape bubble gum and dance in glitter!"
Of course, the wahoo factor depends on the paper you use. On my Col-o-dex card, the ink's properties are subdued. A deep purple predominates with lovely lime green sheen breaking through in the writing and splats. I must have forgotten to shake up the bottle thoroughly before I did my card, because only a little shimmer is showing.
On Rhodia white dot-grid paper, the ink is even more tame. Virtually no sheen is displayed (except in the swipes) and all you see is the purple. I did remember to shake before swabbing, so you can see the blue shimmer in the swab.
Chromatography shows the various base colors in the ink: lavender, pink, and magenta.
Midori MD Cotton paper and a fat ruling pen bring out the gorgeous green sheen in the ink. Clearly, you'll get the best results with broad nibs and paper that isn't too absorbent.
I wrote a longer writing sample in my MD Journal with a TWSBI stub nib. The ink flowed well and sheen shows up, especially in sunlight.
But the best paper to use in conjunction with Hippo Noto & Kiwi Inks V. 1 is Tomoe River Paper. On Tomoe, not only do you get the beautiful green sheen, but all the spectacular colors burst like fireworks in the splats and dribbles. This is definitely an ink you'll want to play with.
You can purchase Hippo Noto & Kiwi Inks V. 1 from the Hippo Noto website ($25.00 for 30ml). The third wave of this ink will ship at the end of January/early February. If you prefer even more wow you can opt for V. 2 which features rainbow shimmer!
(I purchased this ink with my own funds.)
