Pica-Dry® Longlife Automatic Pen Refills are trade-grade marking solutions designed for layout precision on damp concrete, wet timber, and dusty PVC piping. These 2.8mm graphite and pigmented leads eliminate the risk of measurement errors on dark or rough substrates where traditional pencils fail to adhere.
Engineered for Australian site conditions, the water-resistant summer leads maintain thermal stability up to 70°C, preventing lead softening in high-heat storage environments. The refillable system supports workflow efficiency through pre-sharpened leads while meeting ISO 14001 environmental standards and REACH compliance for trade-safe handling.
