Now you can fully experience the cold-keeping power of your Rambler Tumbler for smoothies, slushies, margaritas, and other frozen drinks. The wide, durable straw lets you easily sip the beverage of your choice. It has a molded-in stopper to prevent straw loss, and can handle liquids both thick and thin. Like all Rambler Tumbler lids, this straw and lid are built tough—theyre shatter-proof, dishwasher safe, and BPA-free.
