The Iconic Grog Squeezer™ Marker
The Grog Squeezer™ was born in Italy in 2005, shortly after the release of the brand's first product, the Buff Proof Ink™. While homemade mop marker had been a staple in writing for years, Grog was the first to industrialize and perfect the concept. They engineered a specific tool with a soft, resilient plastic body and paired it with high-performance inks and paints. They also introduced a revolutionary fabric-tip system, more durable than the typical sponge nib found on DIY mop markers, which significantly increased wear resistance and lifespan. This marker wasn't just an evolution of the DIY mop; it was a purpose-built professional tool that offered writers unprecedented control over flow and drips, setting a new standard for street tagging. Grog introduced the Squeezer™ and defined the category. Many have followed, but the original still sets the pace.
Perfect Drips with Grog Squeezer™
The signature feature of this drip marker is its ability to produce long, thick drips. This comes directly from its body design. Unlike a pump-action marker with a rigid barrel that only meters output when you pump, a graffiti squeezer uses a soft, squeezable body to push extra ink or paint toward a high-flow nib as you write. It all comes down to flow control. Both tools use a spring-loaded valve at the nib. In a pump marker, the rigid body means output is regulated only by pumping. In a Graffiti Squeezer™, the same valve is triggered as the nib hits the surface, while your squeeze on the soft body drives more ink or paint to the tip. The harder the squeeze, the heavier the line and the longer the drips. This added output, combined with gravity and the ink’s viscosity, creates the iconic dripping effect. This is why the Grog Squeezer™ is considered the best drip marker: it delivers the right balance of flow and control to master this aesthetic.
Control the Flow: Grog Squeezer™
Flow control on this marker is entirely manual and pressure-sensitive. The squeezable body acts as a direct-control pump system operated by the writer's hand. A light grip produces a standard, saturated line suitable for clean tags. A harder squeeze increases the internal pressure, forcing more ink through the nib and creating fatter lines and longer drips. This tactile feedback allows for dynamic modulation of the stroke mid-tag. Mastering the pressure is the key to controlling the Grog Squeezer™'s output, making it the best marker for drips because the writer has total authority over the effect.
Grog Squeezer™: FMP & BPI Formulas
Its performance is intrinsically linked to the formula it's filled with. The marker is optimized for two main types of Grog refills. The Grog FMP Full Metal Paint™ is a high-viscosity paint perfect for creating thick, opaque drips with a glossy finish. For a different effect, the Grog BPI Buff Proof Ink™ is a low-viscosity, dye-based ink that creates runnier drips and deeply stains the surface. The range also includes specialty inks, like the mirror-finish Grog MCP Mercury Chrome Paint™ and the ultra-permanent Grog SKI Street Killer Ink™, loaded in models like the Grog Squeezer™ 25 SKI.
Grog Squeezer™ in 05, 10 & 25mm Nibs
The Grog Squeezer™ line is available in multiple sizes to suit any application. The Mini 05, like the Grog Squeezer™ 05 BPI, uses a 5mm nib, ideal for smaller, more controlled tags. The 10mm size, found on the iconic Grog Squeezer™ 10 fmp, is the all-rounder, offering the perfect balance of line width and flow for most handstyles. For maximum impact, the 20mm and 25mm models, like the Grog Squeezer™ Mini 20 FMP and the Grog Squeezer™ 25 FMP, are equipped with large, high-flow nibs designed to deliver a massive amount of paint for huge, drippy tags on large surfaces.
Your Custom Grog Squeezer™ (EPT)
For writers who demand full control over their tools, Grog offers the Empty Squeezer. These are part of the EPT (Empties, Parts & Tools) line, providing the same high-quality, squeezable body and high-flow nib as the pre-filled models, but ready to be loaded with any compatible marker refill. The Grog Squeezer™ Mini 10 EPT is a popular choice, allowing writers to create their own custom graffiti mop with unique ink or paint mixes. This modular approach makes it possible to build a tool perfectly tailored to a specific style or surface.
