This Kit includes our Expray Explosive Detection Kit and PDK Explosive Detection Kits and include an extra-large can of See-Through, used to inspect the contents of suspect envelopes and documents. It is a clear liquid that is non-conductive. Simply spray the suspect envelope or document from a distance of 4", getting the document wet. Observe the contents. After the document or envelope is dry, See-Through will not leave any traces or marks. See-Through will not damage ink or address markings. With this complete kit, you can test nearly all of the most commonly used explosives.
