Great for mixing!
Somehow I didn't notice that I had 3 of these sample vials in my cart when I checked out instead of the 1 that I intended, and this blue is a bit dull for my taste (my faves are teal blues like Noodler's Navy) so to use up some of the extra, I did my first ink mixing experiment: a 50/50 mix of this with Sailor Jentle Ultramarine (a bluish purple) and got a fantastic purplish blue! 10/10 would mix again
