Finally, someone said Private Reserve.
I interpreted the subject of the thread to be what inks people find moist reliable but others have taken it to mean things like which have the nicest colors. I think Private Reserve has not got much attention here because it has never been stellar on the first count. The ink changes color in the bottle, gets moldy, the second bottle is not the same color as the first, there are the ongoing mysteries about who is making it where, etc. I have bought many bottles of PR ink and liked most of them but reliability and consistency were not their forte. In contrast the Made in USA Sheaffer inks from 1960 to when they ceased production in Ft. Madison were incredibly reliable. But not super saturated, not dozens of different colors, and few new or exotic colors. I have many bottles of the stuff and it is still reliable -- mold-free and unchanged in color.
