(Brick 20/100) Even though firecrackers are 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 packing. We've seen many grades of firecrackers being produced and we'll onlytake the best for Black Cat. Over the past 50 years, Black Cat firecrackers have proven themselves to be the highest quality and "the best you can get" Case 8/20/100
