Black Ink Detecta-Mark, Permanent Marker Pen, 10 Pk

The Detecta Permanent Marker features a metal and x-ray detectable body and cap, moulded from high-density polyethylene, containing a non-toxic metal detectable additive. The compound can be detected by correctly calibrator in-line metal detection systems. The Detectamark features sureflow ink, meaning the pen will continue to write for several days, even if the cap is left off. This alcohol-based ink will permanently mark most surfaces, including wood, plastic, glass concrete and clean or printed metals. It also features a ventilated safety cap and reversible bullet nib which extends nib life.
