Why you need this marker Delivers clear, long-range visibility so markings are easy to identify at a distance and under low light. Built to withstand heavy professional use: consistent ink flow, abrasion resistance, and a tip that keeps its shape. Refillable design reduces waste and operating cost for frequent, large-area jobs. Key benefits and how it solves problems Consistent performance: High-density fiber tip balances elasticity and hardness to maintain shape, ensure steady ink flow, and resist wear during prolonged use. Reliable visibility: High-contrast markings visible up to 15 meters in daytime. Night-reflective properties improve detectability in dark environments for safer, more reliable use. Large-area efficiency: Designed for broad coverage, this marker handles large-surface marking tasks and industrial applications without frequent replacement. Sustainable and cost-effective: Refillable tank supports more than 50 refills, cutting down on disposable waste and lowering long-term consumable expenses. Important attributes Function: Large-area marking and high-visibility signage for professional and industrial use. Tip material: High-density fiber tip for balanced elasticity, durability, and shape retention. Visibility: Up to 15 meters daytime visibility with high contrast; night-reflective for low-light conditions. Performance: Constant ink flow and wear resistance for extended use. Refillability: Refillable tank designed to accommodate frequent refilling (over 50 refills). Practical applications Construction and roadwork: Marking zones, safety lines, and equipment locations where high-contrast, long-range visibility is required. Warehouses and logistics: Floor and rack markings that remain visible in brightly lit and dim sections of storage facilities. Industrial maintenance and site management: Large-surface labeling, container marking, and temporary signage that need durable, repeatable results. Technical summary Tip: High-density fiber tip — balances elasticity and hardness, maintains shape Visibility: High contrast, visible up to 15 meters in daytime Low-light use: Night-reflective properties for reliable performance in dark environments Coverage: Suited for large-surface and industrial marking tasks Sustainability: Refillable tank supporting more than 50 refills for frequent use This marker is engineered for professionals who need clear, durable, and repeatable markings across large surfaces while minimizing waste and replacement costs.
