Just received my set this morning, I purchased the Stress Relief, Just wondered if any one else had received their's, as the three glass candle jars, seem to have the oil laying on one side of the glass, as though they were put in the box, while the wax was still hot,so one side of the jar is a different colour to the other, if you understand what I mean, Is this normal with the spa set, as I have never had this with all my other Yankee Candles.
