All of our Tealight candles are hand poured using our special low melt formula, a blend of our double refined paraffin waxes and special additives, to insure a quicker melt point which sets up the 'wax pool' quicker, insuring rapid fragrance release. Our Tealight wicks have a 100% cotton core and are made in America by one of the oldest Wick Manufacturers in the Industry. Our wicks are 100% Lead-Free. Our tealights are assembled by hand and are set into High Quality American Made 'Crystal Clear' Polycarbonate Cups (as the candle liquefies it creates its 'true wax color, and light is transmitted in all directions, depending on holder used). We do not use metal cups for our Tealights. Our Tealight Candles burn for an average of 4-6 hours, depending on the colorant and fragrance used. All candles are highly fragranced. ALL our candles have the highest fragrance load allowed by our formulas.
