TAKE YOUR MORNING COFFEE TO-GO. This double-duty, on-the-go drink handler is topped with the Rambler(R) Stronghold(TM) Lid-a leak-resistant, twist-on upgrade that's back with dual-slider magnet technology. This lid easily rotates to fasten for both right- and left-handed users, adding a strong layer between your free-flowing drink and the outside world. And if we're talkin' about where to take it, its elevated handle lets you enjoy cupholder convenience just about anywhere. Please Note: The Stronghold(TM) Lid is specially made for the Rambler(R) 20 oz. Travel Mug and won't fit other Rambler(R) Drinkware models. The Travel Mug Stronghold(TM) Lid has four placement options and plays nice with both righties and lefties, just like all our Rambler(R) Drinkware. Do not use the Rambler(R) Travel Mug Stronghold(TM) Lid with carbonated beverages or for storage of food or perishables.
