A resin silver design dragon backflow incense burner which has a colour changing light to add to the effects. When a cone is lit smoke cascades downwards, through the dragons nose in a waterfall effect and pools at the bottom. For best effects burn indoors in an area away from any sudden air movements. Please note that after burning it is normal for a light oily residue to appear on the oil burner, for this reason we recommend protecting any furniture it is placed upon suitably. The residue can be easily wiped off the burner with a damp cloth. Please exercise caution when burning incense. Only backflow incense cones should be used with this product â€" standard incense cones will not create the desired effect. It is normal for cones to take up to 10 minutes after being lit to start creating the smoking/mist effect. We supply a selection of backflow incense cones in a variety of scents.
