This permanent marker is non toxic and with Sureflow ink, if the cap is left off, it will continue to write for several days. We also sell marker removal wipes.
The body & cap of our Detectamark Permanent Marker are 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.
