Mark-n-doc #'s 1-50, Metric

This kit of 50 numbered evidence markers have scales printed onto each marker. You don€™t need to mark and then place a separate scale down before photographing items of interest. It€™s a two-in-one tool that does double duty. Place the marker and you€™re ready to photograph with scales for reference. And they have multiple punched holes so that they can be firmly secured to vertical surfaces.
