The 660PI marker comes equipped with an exchangeable 15mm chisel-tip and is filled with Coversall ink - a pitch-black, alcohol-based ink which contains synthetic bitumen and provides a permanent, visco-plastic coating.
It is also highly opaque, UV and weather-resistant, quick drying, abrasion resistant - ideal for indoor and outdoor use. The broad 15mm tip offers large line widths - perfectly suited to that classical letter architecture: graffiti.
