Made of durable stainless steel, this flange is designed to add a touch of elegance to any kitchen while also serving its practical purpose. The Italian craftsmanship ensures quality and reliability, making it a valuable addition to your home improvement projects.  The box was opened by the plumber to show me how it worked, we chose to use the old school stopper as we have no disposal.
