At present, large and medium-sized cities and even some counties and towns have formulated regulations prohibiting the discharge of fireworks and firecrackers, and some companies have also developed some salute machines and firecrackers using gas. But because gas needs liquefied gas and oxygen, if you run on the road, you need to carry two cans. Considering safety factors, the transportation department has banned the use of gas cannons in some areas. Now we have invented a pure electronic firecracker, which does not use any gas, is really safe and environmentally friendly, with low noise and realistic sound. Our company specializes in selling this kind of products.
