Cold Insulation

We put the Kat'z Deli tumbler to the test against a standard mug, and the results were surprisingly impressive. Crafted with double-walled stainless steel insulation, this tumbler doesn't just look like a New York City souvenir-it feels like one. While your standard mug leaves your drink vulnerable to temperature swings, this one keeps our Reuben hot, the tangy sauce clinging to the sandwich's meat and cheese just right for savoring every bite. A twist of the handle ensures the coffee stays refreshingly cold, even after hours of sipping. The matte finish and bold cityscape etching add a touch of charm, but it's the performance that steals the spotlight. Though slightly heavier than typical mugs, the durability and insulation make it worth the weight. Whether you're chasing the perfect Reuben or a crisp iced coffee, this tumbler proves it can handle both-and maybe even outshine them.
