My name is Kevin Moody, my children started a candle making company. Candlesbykids.net I would like to know if anyone can help me figure out what these car scents are made of and if I can be pointed in the right direction to achieve this kind of result. They are very strong, if you put one under your seat, they will last for at least a month, maybe longer. We are just trying to expand our product base, any information would be greatly appreciated!
