Grog Squeezer 25mm BPI
Go "All City" with the legendary Grog Squeezer 25mm BPI. This marker is loaded with Grog’s famous Buff Proof Ink—a formula based on high-staining dyes rather than pigments, making it nearly impossible to remove. "The Big Boss" proves that size really does matter, featuring a robust 25mm Stronghair™ Tip that allows you to drop thick, juicy, dripping tags that are guaranteed to stand out.
Built with a soft plastic body for ultimate flow control, this marker is fully refillable and designed for heavy-duty street use.
