This is a brand new in package stereo pair (L+R) of RCA interconnect hi-end cables.  Straight Wire Harmony II cables have been around for years and are considered to be a fantastic upgrade over regular cable that "come in the box" with audio components.  These are $90 cables purchased new.  Beautiful matte green jacket with gold plug ends.  These have never been used.  These are a bargain to upgrade your system.  See my other listings for more Straight Wire cables.
