Incense has been used for centuries to provide a pleasant fragrance, it has been used for meditation, ritual, and to simply fragrance the environment.
Sandalwood incense cones by Earl of East in a brass tin that can used as an incense holder.
As with candles, use caution when burning incense. Keep away from children, pets etc. Always burn on a stable, heat resistance holder designed for this purpose. Make sure all ash falls on a fire-proof surface. Use in a ventilated space but away from open windows, drafts and curtains.
