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! Day or Night Use.
