That's NT BS in general and bad anglosaxon commercial in special. You can buy the same rockets here, but we would never give them such ridiculous names. Here they're called Chrysanthemum Rocket, Golden Burst, Crackling Silver or something like that.
If they sold dynamite and TNT or C4 the names would be appropriate, but they don't, so they aren't.
