Hello! This mug has been hand-painted and hand-built, from red earthenware clay. All of my mugs are covered in food-safe clear glaze inside and out! It can be used in the microwave and is dishwasher friendly. If you want the mug to last forever I recommend hand washing/ not microwaving for long periods of time. Caution when microwaving as the handle or mug may get hot. It's perfect size for a good cup of coffee, juice, or tea!!! My pieces are one of a kind and in many of them, you will find marks left by the handmade process. There's are all a part of the quirky charm that comes with owning a handmade piece. Each mug will not be a exact replica but will be one of a kind! I hope you love it as much as I loved making it!! Approximately is (3.5) inches deep and (4.5") at the widest point
