Handmade in Indiana, these handsome double-wall travel mugs are formed from locally-milled hardwoods laminated into attractive vertical stripes. Individually shaped by turning on a wood lathe, the artful wooden mug is fitted with a manufactured stainless steel interior, which includes a screw-top lid with sliding top opening. The wood acts as an insulator and dapper enhancement to the everyday travel mug. Finished with a hard clear-coat, the wood requires no oiling or maintenance – just hand wash and go! Mug holds 16 ounces and nestles perfectly into your car cup holder. Mugs sold separately. Due to the use of multiple types of native hardwoods, each travel mug will vary as shown in the images above. Wood types may include American maple, cherry, black locust, walnut, oak, hickory, hackberry, and/or ash, each with unique wood grains. Woods are native to North America. The stainless steel insert is imported.
