I purchased this at a Takatori-yaki shop in 2k540 Ueno. It is 10cm tall and 5.5cm in diameter. The surface of the pottery is uneven, allowing you to pour beer and other drinks with a creamy head. - Color: Black and gray gradation - Material: Pottery - Shape: Elongated cylindrical - Inside color: Bright color inside - Quantity: Set of 2 Thank you for looking.
