Big Frig 30oz Tumbler

*** Since these are custom tumblers, it will show they are on backorder, but we need the image before we charge you. ***

The tumbler’s design has been engineered from the inside-out to ensure it’s ready for any challenge you throw at it. Corrosion-resistant 18/8 stainless steel (a.k.a. 304 stainless steel for you fabricators out there) is cold worked for durability and vacuumed sealed for superior insulation. The inner wall is copper lined for more even temperature distribution within your beverage of choice.
