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. Black Cat firecrackers have proven themselves to be the highest quality and "the best you can get." 1-1/2" Loud noise makers. Super Charged Flashlight Crackers. The highest quality standards in our industry are created by 1) using the maximum alloy materials allowed, 2) we use labor intensive methods to provide tighter wrapped and thicker tubes, creating bigger bangs, and 3) 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!
