The YETI® Rambler® 16 oz. Stackable Cup offers a convenient way to save space while enjoying your favorite beverages wherever you go. With its advanced double-wall vacuum insulation, this cup maintains optimal drink temperature throughout the day. Designed for portability, it includes the MagSlider™ Lid to keep your drink safe from spills while on the move. This reliable and durable cup is a must-have for any avid Rambler® fan. Please note that the MagSlider™ Lid is not designed to prevent leaks or spills. I ordered over two weeks ago and still haven’t received after paying $10 for standard shipping. Thanks.
