Specialty metal detectable markers handle the marking jobs a standard marker cannot, while staying findable if one goes missing. The detectable meat marker uses a food-grade ink formula for writing directly on carcasses, fresh cuts and cheese wheels. The detectable UV marker leaves a mark that is invisible in normal light and appears under a UV lamp, for covert asset tracking and tamper checks. The metal detectable jumbo marker has a solid aluminum body and a 1" nib for bold marks readable across a warehouse. The F700 felt tip pen gives a bolder line than a ballpoint for boxes, labels and charts. For everyday marking, see permanent markers, dry erase markers and highlighters, or browse all metal detectable markers. Verify your line with metal detector test pieces, or request a sample.
