A very not-useful color, lol. The first thing I would think about is RK40210 mixed with J. Herbin Bouton d’or. Not as bright as JH but not as dark as RK. I got this bottle just because of the collection set.
Several things that similar to RK40210: drying time (15-20 sec), low water resistant, not so much shading, and wet ink flow. However, Shine bled through iPaper UCCU and somehow all the way through DoubleA. I’m not sure if this is because of the formula from Sailor (didn’t get a chance to get the discontinued yellow) and maybe I’ll put JH to test right next to it.
CP value: ??, since it’s already sold out, but other than getting for the set, I won’t buy this
