Grog Buff Proof Ink [200ml]

Grog Buff Proof Ink 200ml is a dye-based, alcohol-formulated black ink built to penetrate surfaces deeply rather than just sit on top, making tags genuinely hard to fully cover. As the ink that first defined the Grog brand, it delivers permanent, deep black results on painted surfaces, plastics and metal — a reliable refill for markers, squeezers and mops used for demanding, everyday work.
