Tea lights are; by far, the handiest of candles. Lasting four to five hours each they are small enough to fit into the most delicate of candle holders, and due to the metal cup that they come in, safer and easier to replace than votive candles or the like. Tealights can be used for warming oil diffusers, and other devices in need of a small and predictable flame. This bulk 100 pack of tea lights insures that you will not run out of candles any time soon.
