This is a Bizen-yaki single-flower vase. I received it from my grandmother, who collected Bizen-yaki, about 30 years ago, but I never used it. It's hexagonal. The mouth is 3 cm in diameter, the height is 23.5 cm, and the base is 6.5 cm. I can't read the name of the artist. Bizen-yaki lovers, please take a look.
