If you want drips you came to the right place. The Grog BPI (Buff Proof Ink) Squeezer has become the "go to" mop or squeeze marker for many street artists. The "high flow" Grog Squeezer BPI comes in 3 size options - 25mm, 10mm, and 05mm, depending on your technique or taste. Each squeezer is filled with the infamous Grog Buff Proof Ink. Buff Proof Ink is a highly permanent alcohol based "Death Black" color ink with a glossy finish.
These markers are refillable with Grog Buff Proof Ink 200ml Refill.
The beloved Metal Head 04 carries a galvanized steel tip with a 4mm rollerball nib which allows you to write on practically any surface without damaging the marker nib, even rusty and dirty surfaces! The soft plastic of its body squeezes easily for smooth writing and a controlled flow. Refillable with your favorite graffiti grade paint (like Grog or On The Run). This marker is a favorite for train writers or those artists that like to work with traditionally difficult surfaces.View full product details
