Grog Squeezer 10 BPI. The Best Graffiti Mop For Hard To Buff Tags

The Grog Squeezer 10 BPI is considered by many to be the best graffiti mop for applications on any surface, including rough textures where others fail. Its primary technical feature is the combination of a pliable, soft body and a 10mm Stronghair round tip. This robust tip, made from dense mohair fibers, is specifically designed to withstand rough surfaces like concrete, while the body of this 10mm squeeze marker allows for complete control over the ink flow. By applying pressure, the writer can easily achieve a super flow, perfect for producing signature big drips on materials like plastic and painted surfaces.

This is a professional-grade ink marker, factory-filled with 70 ml of Grog’s Buff Proof Ink. Unlike paint, this is a highly fluid, dye-based alcohol based ink designed to penetrate porous surfaces deeply. This creates a truly permanent ink that is famously hard to buff; even if painted over, a ghost of the original tag often bleeds through. The formula is also fade resistant and UV resistant ink, ensuring maximum longevity. This ink is the flagship of the Grog BPI Buff Proof Ink series, renowned for its resilience.

The Grog Squeezer 10 BPI is a fully serviceable and refillable marker built for long-term action. Its 70 ml reservoir can be easily topped up, while the anti-drip rim ensures a clean process. The marker is also equipped with a replaceable nib, allowing the writer to swap out the Stronghair tip once it wears down, restoring the tool to its original performance. Its combination of a durable build and high-performance ink makes it a staple for any writer's toolkit. For more details, visit the official Grog Squeezer 10 BPI page.
