Add a bright detail to any Rambler® Tumbler or Mug with one easy switch. These pop-on, pop-off magnets are dishwasher-safe and pair perfectly with the MagSlider™ Lid, so you can mix and match your coloured magnet with your favourite Rambler® Drinkware 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. Please Note: The Magslider™ Magnets are not compatible with the Travel Tumbler StrongHold Lid.
