The Culver 27 US Fluid Ounce Impulse Tumbler features Superior Vacuum Insulation. Includes Straw for Use with Cold Beverages. It incorporates three of the best forms of drinkware insulation: 1) Double Wall, 2) Vacuum Insulation, 3) Copper Lining. The Double Wall eliminates condensation on the exterior wall while retaining the internal temperature longer through various levels of insulation, as shown in photo. Vacuum Insulation removes all the air between the inner and outer walls. This vacuum practically eliminates convection through which heat or cold is transferred away from its source. Copper Lining on the exterior of the inner wall helps to further ensure beverages keep their temperature for extended periods of time. Copper is a natural insulator, and its placement on the outside of the inner wall provides a maximum benefit. On average, beverages with Vacuum Copper Insulation stay hot for 8 hours and stay cold for 24 hours. Care Instructions: HAND WASH ONLY - Dishwasher may damage product or lid seal. Do Not Place in Microwave, Do Not Overfill, Hot Liquids Can Burn. Do not use bleach or abrasive cleaners containing chlorine to clean.
