For most customers, the insulated shipper in which we sent vials to you initially can be used for returning samples.
Ship to:
Jonah Ventures
5485 Conestoga Ct #210
Boulder, CO 80301
(720) 515-6624
Make sure to email us tracking information (info@jonahventures.com).
For frozen samples in an insulated shipper, 2-day express is usually sufficient. Fed Ex and UPS are typically better than USPS for shipping.
