Made of layers of dyed Birch veneer. I cut it in a way that created the most contrast between the colors. Handle and base are made of African Wenge. The inside liner is a two-part food safe epoxy and comes with a lifetime guarantee for normal use.
Capacity: 22 ounces
The lining cannot withstand boiling water, but hot and cold beverages are okay, including hot coffee. Wood makes a great insulator; so its a good choice for wine, soda, or beer.
Now for the logic part: Do not use in the dishwasher or the microwave!
Hand wash with warm soap and water.
