Telephone Cord Phone Cord Length 10m MC-410W/N This telephone cord is a 6-core, 4-wire cord compatible with most telephones and fax machines, and can also be used with 6-core, 2-wire systems. I purchased this new a few years ago, but ended up not using it, so I am offering it for sale. Please note that the box has some stains due to age (see image 4). To reduce the thickness for shipping, I will fold the box. If you are interested, please consider purchasing. Thank you for looking.
