the duozie tumblers are 2 in 1 tumblers that go from 12oz tumbler to can coolers. The skinny fits cans such as white claws and the thick fits regular soft drink and beer cans!
These tumblers are not dishwasher or microwave safe.
They are double wall insulated to keep drinks hot or cold for HOURS!
Design is baked on at a high heat so they will never crack or peel.
