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 our Magslider™ Lid, so you can mix and match your colored magnet with your favorite 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.  Note:  The MagSlider™ Magnets are not compatible with the Travel Tumbler StrongHold lid.
