This firework is what gave Pyroworx its reputation.   One of the first of the original line up and it made a statement !  If you want to go all out and completely obliterate the sky and get your guests standing in awe, Tour De Force is for you! 
At almost maximum powder weight of 3.9 kilos and 288 shots, this thing will blow your mind !  Still one of my all time favourites. And still used in our professional shows.
