A tumbler is a type of cup that’s used for serving beverages including water, juice, soda, or cocktails. Iron Flask tumblers are made from high-quality 18/8 food-grade stainless steel material. This design makes them easy to tote around wherever life takes you. Use your tumbler for hot drinks like tea or coffee – they’re insulated to maintain the temperature of the liquid inside. Our tumblers also come with lids and straws, making them especially convenient for preventing leaks.

How to Care for Your Classic Tumblers
Cleaning your insulated tumblers is easy. Use a brush to scrub the interior and exterior with warm water and dish soap. You can dry it with paper towels or a kitchen towel. If you’re not pressed for time, you can also leave it to air dry on a dish rack. Hand washing is necessary to preserve the powder-coated finish and keep your tumbler looking new. The extreme heat of the dishwasher can be harmful to the tumbler’s exterior, so always prioritize washing your cup by hand. Thankfully, we make it easy to care for your tumbler!
