This was a gift and has been stored in a closet for a long time. It's an octagonal vase with a beautiful gradation of colors: blue, purple, yellow, and white, just like a peacock spreading its feathers. It's small but impactful, and I believe it's a piece by a true artist. Height: Approximately 17 cm Opening diameter: Approximately 3.5 cm Body width: Approximately 12.5 cm The lid of the original box has water stains on the right side, about a quarter of the way down. Although unused, it's a "yu-sai" (glazed) piece, so it feels like an oily film when touched, similar to glass. I think it's beautiful, but please forgive any oversights. I look forward to hearing from those who understand that it has been stored at home for a long time.
