Tripwire designed and created the original live (real) material explosive detection K9 training kit in 2005 and has since delivered thousands of our custom kits to law enforcement and military units around the globe. We aim to continuously improve upon the kit, with input from our extensive clientele, which has brought us to the latest generation of our kit. We handle each and every product using approved FBI evidence handling techniques and packaged in patented and state-of-the-art OPSAK® odor barrier bags by LOKSAK®. These poly-bags boast of a hermetic seal and are certified waterproof to 200 feet (60 meters). Any item placed inside the OPSAK® bag remains impervious to the elements and retained to the highest degree. The OPSAK® bag offers an absolute airtight seal preventing the re-entry or release of air and microorganisms. Many have tried, but none have successfully replicated our methods and products. Whether our top-notch materials and scents or our U.S. Department of Transportation approved EX Number, there is no equivalent explosive training kit designed specifically for K9 teams available anywhere else.
