This is a tropical fish and under the sea mug. It holds about 12 oz, thin and detailed. There is a beautiful pattern of sealife carved with bubbles and coral. Green sea grass lines the bottom. Clown fish and other tropical fish are swimming in the gradient blue sea background. The mug handle is a curled mermaid tail. Very study and well made, this mug is made from porcelain and high quality glazes. The best part is it is dishwasher and microwave safe.
