It's been a while since I've done any ink reviews, and I don't have as much time to be as exhaustive as I once was, but perhaps this will be useful to someone.
Sailor Bungbox Omotesando Blue
Pen: Aurora Ipsilon Deluxe (M)
Papers: MvL=Mohawk via Linen, TR=Tomoe River,Rhodia=Rhodia 90g ivory.
Camera: iPhone 7
A friend sent me a sample of this ink a while back, and I noticed that is was also available at Vanness, the US Source for Bungbox inks in the US. This is a fairly strong blue, fairly bright. The iPhone image is a good bit darker for sure than the actual image — it's a moderately bright, medium blue. The image in Preview is much closer to the actual image on paper, the one uploaded is shifted darker. As always, images are what they are. If you think you might like an ink, especially for its color, then purchase of a sample to confirm the look and feel of an ink prior to purchasing a bottle is a recommended, though not foolproof, practice. Especially so when the price of an ink is near $45 for 50 ml.
The ink shades well on Tomoe River and Rhodia, and there is a decent amount of reddish sheen on TR in artificial light. The dry times on absorbent paper is quite fast, a good deal slower on the better papers. There could be some show through and/or bleed through problems on the more absorbent papers. There was a little show through on MvL but nothing problematic.
