Keep splashes at bay and debris out with the YETI Rambler MagSlider Lid 10oz— individually sized for YETI® Wine Tumblers. The smooth magnet offers a reliable sliding mechanism. Plus, the magnet is simple to remove for easier, more thorough cleaning, so it can stay in its prime for a long time. This dishwasher-safe lid also adds a barrier of protection to keep wine contained while helping prevent heat or cold from escaping. Please note: the MagSlider Lid is not leakproof and will not prevent spills.
