The body & cap of our Detectamark fine tip permanent markers is moulded from high-density polyethylene, containing a non-toxic metal detectable additive. This compound can be detected by correctly calibrated 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.
Available with Black , Blue or Red Ink
