Sparklers.co.uk offers a Money-Back Guarantee
If you are not satisfied with our sparklers, a refund will be made. We only stock the best quality sparklers in the UK, and are willing to prove this by our guarantee.
For us to honour this guarantee, we ask you to open one pack of the sparklers and test only one sparkler from the pack to start with, if you are happy with sparkler then please carry on have fun with the remaining sparklers. If you are not happy then stop right there and put the remaining sparklers aside with the original packet and then email us on firstname.lastname@example.org explaining your concern.
For us to honour the Money-Back Guarantee only one sparkler should be used and the rest returned with original package, at your expense.
Thank You and have fun.
