This item was purchased from Senshukai and is unused. I feel it might be a bit large for a woman. P.S. I have a smaller lunch jar of the same type. (Photos 6, 7, and 8) This one is 10.5 cm in diameter and 21 cm in height. I remember using it two or three times, but there are no stains. If you would like to purchase this one as well, I will offer it for 2800 yen, so please comment if you are interested. Thank you for looking.
