Diamine Forever Inks use nano-pigments to create a waterproof and lightfast ink with pigment particles small enough to safely use in a fountain pen.
British ink company Diamine has been around since 1864 and their popular inks are affordable, high quality, smooth-flowing, and safe for all fountain pens.
Staff pick! Jean says: " I'm always looking for waterproof inks to pair with watercolor. Diamine's Forever Inks line is really great for this, and I love that the colors can be mixed."
