Well here is my review for the Sailor Bungbox Nostalgia ink. I'd gotten this last year when these were readily available. Sometimes you can find them at Vanness Pen Shop web site, currently priced at $43 a bottle. If you are in Japan, or traveling there, you can shop at the Bungbox store itself.
The usual papers MvL=Mohawk via Linen, Hij=Hammermill 28 lb inkjet, TR=Tomoe River.
The ink is not waterfast or resistant at all. It's not supposed to be, but thought I'd mention it.
In the range of brown inks I own, this one is unusual. By that I mean it doesn't match color-wise anything else I have. Of course I don't have every ink, so it may well be similar to something else. The ink is perfectly nice, but pricey. After a couple weeks in the pen the ink did darken up somewhat since more water evaporated. It's nice either way.
