WORKS WHERE OTHER MARKERS FAIL – Tracer's clog-free ink reservoir tip writes cleanly on shiny, dusty, damp and oily surfaces where standard marker pens skip or dry out. Ideal for concrete, timber, metal, plastic, and plasterboard. 3-COLOUR PROFESSIONAL KIT – Includes one Black, one Blue and one Red permanent construction marker, so you can colour-code measurements, cuts and marks on site. Vivid, high-contrast ink for clear visibility in all light conditions. PERMANENT & WATERPROOF MARKS – Once applied, marks resist water, dust and handling — they stay legible through the job. No smearing, no fading. Suitable for both indoor and outdoor use in all weather conditions. SITE-READY BELT HOLSTER INCLUDED – The dedicated holster keeps all three markers secure and within reach at all times, so there's no time wasted hunting for a pen on a busy site. Fits standard work belts and tool belts. TRUSTED BY TRADE PROFESSIONALS – Designed for builders, joiners, plumbers, roofers and general construction use. Compatible with the Tracer Marking Guide system. Pairs with Tracer pencils, scribes and layout tools for a complete marking solution.
