“Colour Magic / Colour Magical / Colour Magic”
Peacock Crackers lists a product called “Colour Magic” — described as a 16-shot confetti type product that shoots out multi-colour paper streamers / confetti one by one. They list 1 piece per box and a duration (show time) ~ 90 seconds
SKM Crackers shows “COLOUR MAGIC SOUND 1000 WALA” in their catalog / price listings. The phrasing “sound” suggests a variant combining both color/confetti effect + sound.
