Grog Black Magic Ink

Grog Black Magic Ink

Black Magic Ink is an alcohol and water-based dye invisible ink, optimised for Grog Cutter markers.

It reacts only under UV lights, at which point it turns a deep dark brown satin finish.

Ideal for both indoor and outdoor sessions, it works on porous surfaces only such as cardboard, paper, wood, concrete etc.


Always wear gloves to avoid stains on hands. To activate the chemical reaction, the ink must be exposed to direct light. Don't expose or stock the bottle in direct light. Contains alcohol-based solvents, use in well ventilated areas.
