This is a gift, so the price and materials are unknown. The color appears to change subtly depending on the angle, like a gradation or marble pattern. Feel free to comment with any questions or to negotiate the price. I have other obi-dome (sash clips) for sale as well. Due to the New Year's holiday, there may be days when I cannot ship items smoothly. Thank you for your understanding. #Obidome #Obidome
