The team behind Celtic Fireworks have been part of the UK firework industry for many years. Celtic is one of the largest importers of Professional Category F4 fireworks in the UK, and the growing demand for pro-style fireworks among consumers has led them to introduce a range of their professional products as retail fireworks. This brings the quality and power of Category F4 fireworks to the consumer market. The range began with around 15 lines in 2013, but due to its immense popularity, it has since expanded significantly.
