www.sparklersrus.com 20 Inch Sparklers Wedding Package: These 20-Inch wedding sparklers are the most commonly used wedding sparklers. They have easy light tips and are low smoke, with a burn time of approx. 2 minutes. The longer burn time allows weddings with under 150 guests to only need one sparkler per guest. Each wedding package includes a free pack of six 10 inch sparklers to use as lighters, allowing for a much faster lighting process.
