An updated version of the 12 shot classic. Each box contains a great variety of 12 different 40 gram single break ball artillery shells. All 21 shells contain great crackling dragon tails that follow each shell as it rises into the air. Each shell rises to over 150 feet and breaks with some of the best symmetry you will see in a 1.75 inch commercial grade shell. Great quality and value keeps this shell on top of our best selling list year in and year out.
