I've sent 2 samples in. The first time I sent it USPS Priority in the provided cylinder. It took two weeks just to get to Blackstone. The second time I took Blackstone's advice and packaged my cylinder inside a square box. Had my results in 3 days!
According to Blackstone, apparently USPS has a problem handling small round cylinders, but has no problem handling small boxes. Go figure.
