Ray Allen introduces heavy-duty magnetic stash boxes for canine odor training that officers can attach to many metallic surface. Now officers can place a hide nearly anywhere on a vehicle (in the wheel-well, under the car, in the engine compartment, etc.), at any point along a steel stairway, or in numerous locations in a warehouse facility. The stash boxes are made of heavy-duty aluminum and have self-locking lids to secure odor samples. The small stash box measures approximately 5 3/4 x 2 1/4 x 1 1/2 inches - perfect for most drug, NESTT Petrolatum and many other odor samples. The large stash box measures approximately 11 1/2" x 2 1/4" x 1 1/2" - large enough for a bar of C4, stick of Dynamite or NESTT Cloth Sample Bag.
