This phone cord retracts at the push of a button. You no longer have to deal with twisted and tangled phone cord. Two plug-ins (4 wire 4 pin), allow for easy & convenient internet use. Great to take into a campground to retrieve your email, or keep in the back bay of your RV, so it is readily available to use at a "hot site". The cord is heavy duty, ready for outdoor use and lays much flatter than traditional phone cord when extended. Extends up to 30'. Great gift for the traveler who often finds the phone jack on the wrong side of the hotel room.
