A perfectly ordinary blue ink comparable to Pelikan 4001, Sheaffer, or Parker
blue. I won't compare it to intense blues like Noodler's (regular or eel, which
is almost like the old Penman Sapphire. Never mind the unique Baystate Blue) or
even Herbin Eclat, but I can only give it 4 stars because Waterman Serenity Blue
is a little better and in the same price and color class.
