Store brand flat black handset cord. We have sold hundreds of thousands of cords by this manufacturer. We buy them by the pallet, passing the savings on to you. They are made in China (like nearly all handset cords) and have gold plated contacts. They are lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE free.

Length: The maximum practical working length of this cord is 7 feet. Relaxed the coiled portion of this cord is about 18 to 20 inches long, NOT 12 FEET. Add a little more for the uncoiled portion on each end. It is called a 12 foot cord because 12 feet of material goes into the curling machine. This naming scheme is confusing but it's the standard.
