If I could afford it, I'd get the Caffè Bronze TWSBI ECO to load up with Teranishi Nostalgic Honey. The truth is, I really don't precisely *need* more #fountainpens or #inks.
One blue CO is EF, for writing in my #Filofax. The other blue ECO is 1.1 mm stub italic, for writing bank cheques. The red ECO is M, for crossing-out. The yellow ECO is B, for highlighting meeting documents. I also have a clear ECO F, filled with Teranishi Antique Black, but want to replace that with a black ECO F.
