Fast, spill-resistant drying: waterproof ink dries in about 3 seconds and forms a stain-resistant shield even on damp surfaces. Saves time and avoids smudges so markings remain clear after application. Durable, weatherproof performance: high-performance ink produces vivid, long-lasting marks that resist harsh weather, road debris, and temperature changes. Ideal for reliable tire and equipment identification in outdoor and high-use environments. Reinforced high-density nib: a stable fiber tip delivers crisp, controlled lines on curved tire surfaces. The advanced nib design keeps ink flowing smoothly without blotting or contamination, for precise tire markings, wheel detailing, and custom designs. Refillable ink reservoir: built to be refilled rather than discarded, reducing waste and operating cost. The refillable design supports repeated use (50+ marking cycles) while maintaining consistent ink flow and results under heavy or repeated marking demands. Multi-surface compatibility: formulated to mark rubber, painted and bare metal, and a variety of outdoor materials. Creates clear, weatherproof lines on tires, machinery, tools, and other equipment. Who benefits: contractors, automotive shops, fleet managers, and makers who need durable, visible identification that lasts through rough conditions. Practical applications: 1. Tire shops and garages — quickly mark tire positions, work status, or matching sets during inspection and mounting without waiting for ink to dry. 2. Fleet and asset management — label tires, rims, or outdoor equipment for inventory, maintenance schedules, and theft deterrence with marks that hold up in all seasons. 3. Customization and detailing — add crisp, precise accent lines or lettering to wheels and rims for shows or restoration work where clean, repeatable results matter.
