Scented candles are everywhere this Christmas but not many will last as long and give off as pure a scent as the dense aromatherapy candles from Crate & Barrel. The three-wick candles are scented with essence of thyme, fir and vanilla, aloe and balsam, with hints of cucumber, carnation and musk coming through. They come in round or square shapes, and various heights. Prices range from £23.95 to £60.
