WHEN A STRAW BETTER SUITS YOUR SIPPING STYLE. Our wide, durable drinking straw makes this the perfect lid for margaritas, slushies, ice coffees, sweet tea, and ice-cold H20. Unlike other insulated cups with straws, the Rambler Straw Lids are built to last and have a molded-in stopper that holds your straw safely in place. And just like our other Rambler Lids, it’s shatter-resistant, dishwasher-safe, and completely free of BPA. Please note: This product is not compatible with the Rambler 20 or 30 oz. Travel Mug with Stronghold Lid.Please note: Do not use the Rambler Tumbler Straw Lid with hot beverages.
