Glass candles are in 8 oz clear glass jars with a pewter lid. They are made out of natural 100% pure soy wax, cotton wick free of zinc and lead, non-toxic fragrance oil. Handmade in Toledo, OH. The approximate burn time is 40 hours. Don't forget to read the care instructions and don't forget to trim the wick before each burn, so the candle can deliver a clean soot-free burn.
