CLASSIC AND VERSATILE FOR YOUR CAMP COCKTAIL AND NEAT BOURBON. The RamblerA(R) 10 oz. Lowball is the ideal drinking companion. Easy to stack and store, the Lowball&&';;s double-wall vacuum insulation will keep your hot drinks hot, and your cold drinks cold longer than standard drinkware. Enjoy your evening whiskey by the fire, and refill with coffee the next morning. Like the entire RamblerA(R) Drinkware Family, the Lowball and included Magslider(TM) Lid are dishwasher safe for easy cleaning. While the magnet slider adds an additional barrier of protection to keep drinks hot or cold, this magnet slider is not leakproof and will not prevent spills. 18/8 STAINLESS STEEL Made with kitchen-grade stainless steel, so they&&';;re puncture- and rust-resistant. DOUBLE WALL VACUUM INSULATION Keeps cold drinks cold and hot drinks hot until the last sip. DISHWASHER SAFE Because no one needs more work to do. STACKABLE Save storage space when you remove the lids. (888830273586)
