These specialized pyrotechnic devices are meticulously designed for safe use in environments where traditional fireworks are not suitable, such as theaters, concert halls, ballrooms, and meeting venues. Engineered to perform reliably in close proximity to audiences, most of these devices are safe for use within 15 feet of spectators. This careful design ensures that spectacular effects can be achieved without compromising safety, allowing for dazzling displays and immersive experiences even in more confined or sensitive settings.
