Description Sky Lanterns are essentially miniature hot air balloons. At the heart of each lantern is a pad with fuel that, once lit, will lift the lantern into the sky with a warm white glow. Crafted using translucent, fire-retardant, 100% biodegradable material. To achieve the best effect, at least 10-20 should be used at one time (the more, the better). Sky Lanterns are a fantastic wedding sparkler alternative, if your wedding venue does not allow sparklers!
