Bottled Ink
Bottled ink for fountain pen use. Most inks are dyes (coloured water) that wash out of pens easily, but are also more likely to fade with time. Document inks contain nano pigment granules that bind to paper permanently, so are good for legal use, addressing envelopes and sketching. Calligraphy, acrylic and India inks use larger pigment particles and are not compatible with fountain pens.
