Czech surplus green flares. Travel hundreds of feet leaving a green trail.
26mm flares in either the original 10 round Czech military packaging or a convenient 3 round pack. Heavy cardboard and a wax coating makes the box about as impervious to the elements as you could want. The 3 round pack lets you try them for one low price.
Requires 37mm to 26.5mm adapter!
Authentic Czech Military surplus.
This has to be shipped HAZMAT!
