The Ferndale Tumbler
This design is made from Michigan Hardwoods and includes a 1.5 Pint Mason Jar with a lid. The U.S Made mason Jar slides in to fit snugly, and can be capped off while on the go. Made from premium Michigan Hardwoods and utilizing sophisticated joinery, this is perfect for those of us that just can't stop drinking out of mason jars. Oh, also its a DAMN COASTER. If your drink is unbearably hot or cold the glass heroically acts a heat sink so your lips don't have to.
