Received this as part of a larger order with Norne. Composition was stated from Trevor as being "Silver + Cu Fusion". I believe it is a 4-wire. Total length from tip to tip of each connector is approx. 49.5". Eidolic connectors. Comes with Norne storage pouch (don't know/can't tell if real leather or not) with magnetic button closure. Cable has never been used, save for ensuring operability. Have way too many cables, so trying to find this wonderful cable a home where it will be used! Happy to answer any questions!
