Our Folding Photo Evidence Markers feature an attached photo scale which may be extended into multiple configurations. Each 3½” x 3” marker is constructed of durable nonreflective yellow plastic with numbers and measurements imprinted in black. Each marker includes two hinged attachments which may be configured into multiple shapes. This is the ultimate photo evidence marker. Multiple numbered sets are provided. Optional zippered cases are available with capacities of 20 or 50.
