You found the coolest vintage phone. It has this round thing in the middle that you put your fingers in and twist around in order to dial it! It is so cool! But then you go to plug it in and it's got this really short phone cord that's built-in! Don't freak out - this coupler easily connects that built-in cord to a separate phone extension cord. The Belkin PRO Series Modular Telephone Cord Coupler pairs two phone cords, extending your existing phone cords.
