The name really does say it all with this one.
Thunderous Finale is a 100-shot beast designed for one specific purpose: to end your display with a wall of noise and aggression. It doesn't do "gentle." It packs 810g of powder into a rapid-fire sequence that empties the tubes in just 30 seconds.
You get a chaotic mix of screaming whistles, crackling clusters, and heavy titanium salutes. It is fast, frantic, and deafening. Being a 1.3G firework, the bursts are sharp, and the thuds are deep.
If you want your neighbours to know the show is definitely over, this is the button you press.
