These are specially designed to create smoke that cascades downwards, pouring dramatically down the tower with a stunning effect that will catch your customer's eye. 

Once you have lit your incense cone, it will begin to smoke, the incense is heavier than air and it will fall dramatically in swirls and twists, through the hole and down over the item, to pool at the bottom. It is incredible to watch and very relaxing. 
Backflow Incense Burner is suitable for home, office, teahouse, meditation, yoga studio... 
These have a switch underneath to turn on and off the flashing lights battery operated.
Cones are purchased separately 

Keep out of reach from children and pets, do not light next to anything that may be flammable.
