The Pleson USB C Charhing cable came packaged in zip lock style bag. The cable is constructed of shielded cable with molded plastic ends. Both ends have strain relief but the USB C end is much more well constructed. As far as I can tell this cable is USB C compliant.
If you are looking for a USB C charging cable, this one should get the job done.
