Swig These are truly a HAPPY MUG!! Kick back and relax with your favorite drink in one of these 18 oz. creative-artsy mugs! Each Swig Life Mug keeps drinks cold up to 9 hours and hot up to 3 with its double-wall, vacuum-sealed copper coated insulation. The non-slip silicone base keeps your cups from tipping or making too much noise when you set them down.
The newly-designed lid is BPA free, spill resistant and shatterproof. These clear lids seal tightly with a rubber seal gasket while allowing you to see inside.
The straw friendly opening can be covered with the sliding closure to minimize spilling.
