black and blue

Noodler's Black and Blue is a classic blue-black ink known for its high water resistance and partial bulletproof properties, where the blue washes away but the black core remains legible. It offers a wet flow with medium to low shading, normal viscosity, and forgery resistance against solvents and check-washers. This ink suits users needing durable writing for documents or left-handers avoiding fast-dry inks, though its longer dry time requires patience.
