Our Salt Tea lights are designed to accommodate the size of the common candle. They can be used with any of the regular, scented, or colored candles. Just put in the candle light it up and enjoy several hours of cozy and refreshing light. We suggest a long stick of Match for burning the candle to avoid any injury. Suitable for Sauna rooms, massage rooms, or use for Candlelight dinners, in the bars, or else everywhere you want to make the atmosphere clean, healthier, and romantic as well.
