Tealight Candles, by design are generally considered to be a one use candle. Granted, this one use can have a duration of up 7 hours with the extended burn tealights, but most people find that they are the perfect size for a casual get together, party, peaceful reading session, or long soak in a hot bathtub. What’s perfect about them is that they can easily be tossed and replaced with little to no mess. New scent, new color, new atmosphere. Simple as that.
