The INTEGRA 30012 is a 4-pack of chisel-tip permanent markers supplied in assorted ink colors: black, red, blue, and green. Each marker delivers waterproof, smear-proof ink suited for labeling, marking, and job-site notation tasks. The chisel tip allows both broad strokes and finer line work depending on the angle of application. At 0.25 pounds for the pack, these markers are lightweight enough to carry in a tool pouch or service bag. Tradespeople and technicians use them for marking pipe, conduit, ductwork, and equipment during installation and service calls.
These markers are well-suited for general trade use across HVAC, plumbing, electrical, and pool service applications. They perform on a wide range of surfaces including PVC, copper, galvanized steel, and cardboard. The waterproof ink resists smearing after drying, making markings legible even in damp mechanical rooms or outdoor service environments. The 4-pack format keeps spares on hand without bulk.
Designed as a general-purpose permanent marker for trade and industrial marking tasks across multiple surface types.
No tools or trade license required for use. Allow ink to dry fully before handling marked surfaces in wet or high-humidity environments. Cap markers when not in use to prevent tip drying. Store horizontally or tip-down to maintain ink flow.
