Introducing Swig! We are changing up the tumbler game with our tumblers.They're perfect for vinyl personalization. VACUUM INSULATION - SWiG drinkware uses double walled vacuum sealed insulation technology, meaning the space between the stainless steel walls is void of matter. With no medium for heat to transfer, your drink's temperature will not be impacted by the temperature outside the container. COLD UP TO 24 HOURS / HOT UP TO 12 HOURS - The double wall vacuum sealed SWiG drinkware will keep your beverage cold up to 24 hours and your drink hot up to 12 hours. 304 GRADE - 18/8 STAINLESS STEEL - SWiG drinkware is crafted from 304 grade 18/8 stainless steel. All drinkware is BPA free, FDA approved, highly resistant to rust and to absorbing odor, taste or bacteria. They are easy to clean by hand. BPA FREE PUSH-SEAL LID - The clear lid seals tightly while allowing you to see inside your tumbler. Dishwasher safe & shatter resistant. COPPER COATED INNER WALLS - SWiG's double-layer stainless steel inner walls are copper plated, which provides an additional barrier against heat entering or exiting the vessel. SWEAT FREE - The double wall vacuum insulation prevents condensation from ever forming on the exterior. Hot liquids will not impact the exterior, either. This means your SWiG drinkware will always be comfortable to hold and never make a watery mess in your bag or on your table. CAPACITY - Holds up to 9oz.
