Naturo Himalayan Rocksalt Tea Lights are made out of rocksalt in shapes such as Heart, Star, Apple and Cube with a slot in the center to hold a candle. When lit, they emit healthy negative ions to cleanse and improve the quality and freshness of the air. Himalayan Rocksalt Tea Lights create a relaxing ambience with dim light. Naturo Tea Lights are generally used in spa rooms, bathrooms, for décor in the windows and door-step at night, and can also be placed in the kitchen.
