Φ83mm (drinking opening) x H76mm W112mm (including handle) Capacity: 320ml Weight: 190g Material: Stoneware Country of Origin: Vietnam Dishwasher & Microwave: Safe Oven: Not Safe Stoneware, also known as "semi-porcelain" or "yakishime," is a type of pottery fired at a high temperature of 1100-1250°C. It has properties that are intermediate between earthenware and porcelain. Because they are all handmade, there are individual differences in shape, dimensions, and color even among the same products. Also, all mugs have a small hole inside the handle. This is unavoidable in the manufacturing process and is not a defect. This hole will not lead to cracks or chips. Wash with a soft sponge containing a mild detergent. Do not use abrasive sponges, metal scrubbers, or cleansers, as they may scratch and damage the product. Color: Blue Glass/Cup/Wine Glass: Mug
