The first person who arrives at a crime scene can be very important, by using the First Response Evidence Markers at the crime scene they can now clearly mark all potential evidence as it is found.
The markers come in two colors (Florescent Orange and Florescent yellow) which help mark different categories of evidence. The compact size (1.5" x 3.25") allows them to fit easily in a pocket or crime scene kit ready for use. Made of thick rubber-like vinyl that's durable and easy to clean and decontaminate
With the markers in place they provide an excellent overview of all the evidence prior to numbering it. The markers will not blow away in windy conditions.
The First Response Evidence Markers retails for $11.20 per set (20 markers per set) and is available through EVI-PAQ Innovative Crime Scene Products.
