Acacia wood lid. Acacia is a wood that does not require any treatment that is harmful to health and is known to last over time. Using natural wood also means that each mug unique.
Solid sandstone mug. This material has been known for centuries and is extremely resistant to the knocks and stains that tea can cause. A daily ally, stoneware can be washed in the dishwasher and is microwave safe.
