I feel your pain, i'm not having any luck with them either. I've tried Mc Apple and Coconut Lime both of which I consider to be strong fragrances. They work great in my tarts but like I said no luck for me as Smelly Jellies. The McApple lasted 2 days, the Coconut Lime about 2 weeks. Really frustrating and have tried several different times with the Mc Apple, because someone wants to place an order after smelling the one that I gave to my sister for testing. Little did they know that they happen to get a whif on the first day. I'm embarrased to tell them of the short life. I figure there must be a trick to this. Wish I could figure it out though. Any help would be appreciated.
