Our magnetic numbers, classes and panels are made from super-thick 30 mil magnetic sheet in either a semigloss or gloss finish. They're easy to apply, easy to clean, and will stand up to nearly any condition you throw at them. They have seen duty all across the US and Canada in autocross, rallycross, and track days. Inside and outside corners are rounded to eliminate tearing, and all digits are cut using computer-controlled cutters to ensure consistency in each set.
