This is a set of five (5) 6-foot USB cables, USB-A to USB-C. They are the new 'standard' charging cable for many new cellphones, tablets, and many other devices. The cable covering is braided nylon for maximum strength and flexability. The core is made of tinned copper stranded wires and is foil-shielded to avoid interference. These will be used in our vehicles and in the home for charging our tablets and other equipment.
