I typically love Candlescience and all of it's products but this time I am very disappointed. Right now I have about 14 of these tins that are rusted. I had read some reviews that mentioned it but I have found out first hand that they were correct. As long as you DO NOT USE a FO that has vanillin the cans are fine but anything with vanillin will cause the can to rust. I thought mine were okay because it took about 3 weeks for it to really show up. Now I have product that I have to throw out. I cannot promote a product as safe and healthy and expect customers to buy rusted candles. Candlescience you tell us whether it has PROP65 warnings and you let us know whether a FO performs well in soy, and you even list the vanillin percentage but why don't you also tell your customers that it will cause them to lose product if they use it in the tins? I have items in my cart and right now I'm not sure I want to purchase them. You received 2 stars because the tins are okay in some cases otherwise it would have been a 1.
