Brother Model PCI-1 Multifunction PC to Fax Machine Line Cable Cord Link . Shipped with USPS First Class Package. I ACTUALLY KNOW NOTHING ABOUT THESE THINGS AND HAD TO OPEN THE BOX FOR THE FIRST TIME TODAY TO FIND OUT WHAT WAS IN IT.  THIS ITEM WILL BE SHIPPED TO YOU IN THE SAME BOX I RECEIVED IT IN.  PLEASE LOOK AT PICTURES TO MAKE SURE THIS IS WHAT YOU MIGHT WANT.  STILL IN SAME SEALED PLASTIC BAG.
