Our Yuzu Rouge perfumed candle weighs 180 gr/6.35 oz and burns for approximately 40 hours. Burning directions are printed on the package; for an even burn and to avoid forming a wax “crater” you should allow the wax to melt evenly to the glass before extinguishing it (minimum two to three hours burn time each session). You should also trim the wick of your candle before each burn to prevent generating excessive soot.
