The candle you don't have to light! This "Smelly Jelly" lasts for 13 weeks or more. Just remove the lid and the scent is disbursed into the air. You can rejuvenate the scent by stirring the "jelly" and when it starts to get a little dry you can add water to it to plump it back up. When finished with the product, discard the rest of the "jelly" into the trash and you are left with a stunning jar that can be washed and reused!
