Inferno Ink 1000ml (Black) – Permanent Graffiti & Marker Refill Ink

Inferno Ink Black is a high-coverage, ultra-permanent ink made for graffiti writers, calligraphy artists and street art use. Supplied in a 1 litre / 1000ml bottle, it’s ideal for refilling multiple markers, mops and squeezers or keeping as a studio bulk refill.

Expect a deep black finish, reliable flow and strong adhesion across common surfaces like metal, plastic, glass, wood and painted walls. Works well for tagging, outlines and high-contrast hits where you want a solid, readable black.
