In this very unlikely case we advise you to leave the particular firework where it is and do not return to it for at least 24 hours, after doing so take some pictures of the misfire for our reference and then totally submerge in water for a further 24 hours before placing in your normal black bin.

Please do then use our contact us page and get in touch, we will be happy to take a look at the pictures before passing it on to the manufacturer and getting you a full refund.
