Perfect for Bonfire night (Guy Fawkes), Birthdays, Weddings, Baby Shower, Halloween, New Year and Christmas All of our goods are of the highest quality and have gone through additional testing enabling them to be sold as hazard 1.4S (UN0337) rather than the higher hazard 1.4G (UN0336). Attractive burn on the fireworks will fascinate kids, though it is advised to keep these fireworks away from kids. The burn is relatively clean as we have formulated and created them without any additional bulking agents.
