Tip for consumers: Stay away from YLEO, the oils ARE NOT seed to Seal. The oils are too heavy(diluted)for diffusers and cause buildup that's hard to completely eradicate. Once you've purchased something from YL, dont plan on any customer service if you have problems.
Tip for consumers: DO NOT UNDER ANY CIRCUMSTANCES SIGN UP WITH THESE CROOKS!!! Unless, that is, you like throwing your money down a big black hole.
