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. See what size Rambler® Straw Lid fits your Rambler®:Medium: 16 oz. Pint, 20 oz.
