Even though firecrackers are a very old, very simple type of firework, we take our firecrackers very seriously. Each batch produced is checked for loudness, dud rate, string consistency, labeling and packaging. We’ve seen many grades of firecrackers being produced and we’ll only make the best for Black Cat. 1-1/2″ Loud noise makers. Super Charged Flashlight Crackers. The highest quality standards in our industry created by first, using the maxium alloy materials allowed, and second we use labor intensive methods to provide tighter wrapped and thicker tubes, creating bigger bangs, and third even though the generally accepted dud rate for generic chinese firecrackers is 50%, our own Black Cat criteria only allows for a 5% failure rate! Day or Night Use.
