Offered in a version that marks in temperatures from -40 to 212oF (-40 to 100oC), the permanent marker comes in six colors: red, green, yellow, blue, black and white. It is designed to mark on most surfaces, including greasy surfaces, and will not smear on steel, iron, aluminum, plastic, rubber, vinyl, glass, concrete and wood. For a limited time, the manufacturer is offering free samples to anyone interested in testing the marker.
