The Iron Flask 16 oz Classic Tumbler is the perfect insulated tumbler for your morning coffee, your evening glass of wine, and everything in between. This double-walled stainless steel tumbler keeps your beverages cold for 12 hours and hot for 3 hours without the funky metallic taste or breaking a sweat. Apart from the plastic lid, we’ve included two stainless steel straws and two plastic straws so you can have options when it comes to sippin’ your drink, plus two straw cleaning brushes to keep them like new.
