These are long sparklers (~30 cm / ~12 in) that are formulated to emit coloured spark effects (red, green, blue, or multi-colour) rather than just white/silver.
Because of their size, you can expect longer burn time compared to shorter ones (often around 20–40 seconds, depending on quality).
Many vendors sell them in small boxes (5 pcs per box) or in multi-box bundles.
Useful for events needing dramatic visual flair (weddings, stage exits, photo backdrops, crowd effects).Safety & Handling Notes (for 30 cm Colour Sparklers) Hold securely at the base — the stem will get very hot. Keep distance — have spectators well back (2-4 m or more) due to stronger spark output. Use outdoors or in large well ventilated space. Light one per hand; do not light multiple together. Disposal — after burn, keep in bucket of water or on nonflammable surface until fully cool. Avoid obstacles and flammables in the path or overhead (cloth, decorations, vegetation).
