Natural Candle Supply. You will have to look at each one to see which is body safe, as all of them are not. I used DB previously which was safe but the current one is not, so they change with suppliers so you have to be checking all the time.
I really like Bigtreesupplies FOs. Reasonable prices, great description for each FO, customers can leave a review, etc. I never bought a "dud" FO there.
