Produktserie: Stealth Ink

Stealth Ink came out of Prague and built a cult following in the European street art scene around one idea: ink that starts invisible and darkens permanently under UV light. Applied, it reads as pale or almost clear — exposed to sunlight, a chemical reaction kicks in and the marks develop into a deep brown to near-black stain that soaks into porous surfaces like concrete, stone, and wood and becomes extremely difficult to buff or remove.

Available as pre-filled squeeze mops and chisel markers, plus refill bottles for loading into your own marker setup.
