The order was delivered promptly, however, I purchased 40 packs 4packs of coloured wedding sparklers. When they arrived, I couldn't wait to try them out. To my disappointment, the colour does not change at all when lit. I tried two just to be sure that I hadn't got a dunce one and neither of them changed colour at all. In fact, they don't really burn impressively at all and have quite a sad sparkle to them. I am bitterly disappointed by this as I thought they would be a wonderful addition to my wedding on the 5th of November as we cannot afford to have fireworks.
