Van Dieman's Ink is an Australian company that designs and formulates its own products in Launceston Tasmania. These inks have been tested for viscosity and flow quality and are suitable for all major brands of fountain pens, and are also suitable for dip pens and brushwork.
Van Dieman's Pigment Inks are more water-resistant than their dye-based counterparts. These rich, vivid inks contain free- flowing particles that cling to the cellulose fibres in paper. Be aware that pigment inks are hard to wash after drying so only use in fountain pens approved for pigment or India ink, and ensure to flush regularly and thoroughly.
