RSVP Endurance Stainless Steel Drinking Straws are a novel addition to cold summer beverages and dinner party cocktails. The reusable straws are great with lemonade, iced tea, and blended drinks like smoothies and margaritas. Features as one of Oprah Winfrey's "favorite things," these stainless steel drinking straws are a great alternative to wasteful plastic straws. These straws are safe for the sink or dishwasher safe. Also available from RSVP is a cleaning pipe made especially to fit inside and clean these stainless steel straws.
