This ink is exclusive to Yoseka Stationery in Brooklyn and made by a Taiwanese company, Ink Institute. They were originally best known for their custom-order inks, and you can still order those by providing an RGB value if you’re willing to pay for shipping from Taiwan. The price for Qing Purple is $20 USD for 30ml. Yoseka will also sell you samples if they’re in stock. I bought a sample when I visited in-store.
I noted when I tried the ink at Yoseka that it seemed muted and dusky, not usually my thing but worth trying. I didn’t get the green sheen displayed on their site in writing. It’s a very dark purple, and I don’t think I’ve tried anything quite like it. The undertones are grayer on some paper, and warmer on others. The closest inks I’ve tried are shimmer inks:
- Diamine Deck the Halls
- Diamine Mystique
Here are writing samples with a Leonardo Momento Zero M nib.
If you zoom in, you’ll notice the lines aren’t crisp/filled.
Iroful paper really brings out the richness of the color.
The ink is definitely eggplant-colored but less saturated than I prefer. The smear comes from disturbing the paper about five seconds after I wrote the sample. Otherwise, it’s average flow and doesn’t feather or bleed. Dry time is faster than I expected. I don’t think I need a full bottle, but it was fun to play with!
