Grog Cutter 08 BMI


This marker is filled with Black Magic Ink, an invisible blend that reacts with UV rays, making it an intense dark brown color.

– Hard plastic body
– 8mm Quickflow chisel tip in polyester
– Anti-drip closure cap, to keep it in your pockets.

The black magic ink will darken as much as any light absorbs, you can write outdoors without being seen by anyone: black magic ink will activate only after absorbing enough light.
Cutter 08 BMI is easily refillable, always with the Grog Black Magic Ink 70 replacement.

Available in 1 color.

Warning: Color intensity is determined by the amount of light absorbed by the ink and may vary depending on whether it is used outdoors or indoors.
