RL233S – Supernova Cans Nishiki Kamuro (1.75 inch) deliver one of the most breathtaking effects in pyrotechnics—the Nishiki Kamuro, a Japanese-style break known for its incredibly long hang time and graceful golden willow descent. This effect is difficult to capture on video, but in person it fills the sky with a slow-falling, shimmering display that’s perfect for finales or elegant segments of a show.  Safety Note: Due to the nature of this effect, use caution when shooting. Under certain wind or humidity conditions, stars may descend low or even reach the ground.
