These backflow incense cones can be used with a backflow burner to create wonderful smoke flow displays. Each canister contains 24 cones within the resealable tin, with an approximate burning time of 20 minutes per cone. 

Backflow incense cones are designed to flow downwards, rather than upwards, therefore creating a misty ambience. These cones can also be used with a traditional burner; however, it will not create the same backflow effect.
