The "Super" way to keep your drinks just the way Grandpa likes it! Our 20 oz tumbler boasts double insulation, leaving hot beverages toasty for up to 6 hours and cold ones cool for up to 24 (which is more than enough time to catch the bad guy maxing the thermostat!) Plus, it's BPA free, ships with a lid, metal straw, and a cleaning brush! It's easy to say that this tumbler is definitely "Grandpa-approved"! This tumbler is not dishwasher or microwave safe.
