I am interested in sourcing a specific type of refill for a rotating Roman candle gun that operates on batteries. The product I'm looking for should include a total of 375 shots, providing a vibrant and engaging display for both casual users and enthusiasts. It's important that the refill is designed to fit the model of the cannon I currently have, ensuring compatibility and ease of use. Additionally, I would appreciate any details you can provide regarding the product's quality, safety standards, and pricing. Information about lead times for production and availability would also be helpful, as I aim to make a timely decision for upcoming events. If you have any catalogs or specifications for similar refills, please share that as well. Looking forward to your prompt response!
