When the job gets rough, the Grog Stronghair 25 EPT is the tool you need. These 25mm replacement tips are crafted from durable mohair, a high-strength textile designed to withstand the friction of textured and abrasive surfaces.
Unlike standard nibs that might fray on brick or stone, the Stronghair is built for "aggressive" use, ensuring your lines stay thick and consistent even in the harshest environments.
Technical Specifications
Size: 25 mm Wide.
Material: Heavy-duty Mohair textile.
Compatibility: Designed specifically for Grog Squeezer 25 markers.
Optimal Inks: Engineered to work perfectly with Buff Proof Ink (BPI) and Street Killer Ink (SKI).
Packaging: Sold as a 2-pack.
Key Features
Rugged Durability: The mohair construction is significantly tougher than standard fabric tips, making it ideal for concrete, rusted metal, and rough wood.
Maximum Ink Flow: Despite its toughness, the EPT tip maintains high porosity, allowing for the massive, saturated drips that Grog Squeezer users demand.
Easy Installation: Swapping your old tip for a Stronghair is quick and mess-free, extending the life of your marker body.
High-Performance Pairing: While it works with most paints, it is optimized for alcohol-based inks, helping the pigment "bite" into the surface.
Pro Tip
If you are painting on smooth surfaces like glass or plastic, a standard Flowtex tip might be smoother. However, if you're hitting the streets and dealing with unpredictable textures, the Stronghair 25 is the essential upgrade to prevent your nib from tearing mid-session.
