With the Yeti Magslider Replacement Kit, you can add a bright detail to any Rambler Tumbler or Mug with one easy switch. These pop-on, pop-off magnets pair perfectly with Yeti's dishwasher-safe MagSlider Lid so you can mix and match your coloured magnet with your favourite Rambler drinkware either by the hour, or by the day. Not to mention, it’s a pretty handy trick if you’re aiming to prevent drink mix-ups.
