Lady Bugs - Pack of 3 - one of the most popular flyers on the market.
We have managed to get these from multiple different brands over the last 10 years or so, the most recent being the new range from Dominator Fireworks.
These (usually, some effect variation each year) spin on the ground, glow with silver or red sparks, then shoot up into the air with a loud whistle!
Awesome effect.
Please make sure you let them off on a very flat smooth surface (like concrete or a sheet of plywood)
