This “katiusza”-type battery delivers a rapid sequence of 25 shots, each producing a distinctive whistling and screeching effect, making it an excellent choice for adding dynamic energy to your show. With its F2 safety category, this multi-shot firework is intended for adult use and fits perfectly as a supporting element within larger displays or as a spirited sound accent during celebrations.
