"Tobacco tar oil" ? Sounds nasty. Can I get mine with a side order of burning paper? Anyways, I have ordered from Chinese vendors several times. First advice is use Paypal. Second advice is be patient, it takes a few week usually. Prepare for a language barrier if you run into any issues. I have purchased Hangsen liquids and been very pleased, the RY4 is really good. Never dealt with festec but ordered vaporbreak without issue.
