The Original Yankee Candle Large Jar Candle provides up to 150 hours of consistent room-filling fragrance and now has a wax formulation designed for a cleaner burn — that means less soot, less tunneling, and an optimal fragrance performance. All iconic Jar Candles are poured with a premium plant wax blend and the finest quality ingredients from around the world, with no added parabens, phthalates, formaldehydes, or sulfates. Yankee Candle fragrances are developed and tested in an energy-efficient, Green Lab-certified facility and are crafted with over 50 years of passion and expertise. The Yankee Candle Company, Inc. strictly follows international safety standards and rigorous testing set by the IFRA and ASTM. For best results, trim the wick to the length stated on the bottom label; burn until the entire top layer becomes a pool of liquid wax from edge to edge; always burn on a heat-resistant surface, away from drafts, and never leave unattended; and replace your candle when only ½ inch of wax remains.
