Comments about 10" Color Sparklers:
I bought these for a non-display purpose, for which they were fine. As a display item, I would have found them disappointing - they barely sparkle as they burn.
Merchant Response: As noted in the review, color sparklers do not "sparkle" as much as a traditional gold sparkler. Because of the addition of the color compounds in the sparkler composition, they tend to burn with more smoke and a less sparkle, but with the addition of the red or green color. These are really made for backyard festivities like July 4th, Diwali, or New Year's Eve parties. They are not well suited for more formal events such as weddings. When using sparklers at a formal event, always use a gold sparkler.
