Add a bright detail to any Rambler® tumbler or mug with one easy switch. These pop-on, pop-off magnets pair perfectly with the dishwasher-safe 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.
