Approximately 30 centimeters. This is a rare cushion I received from a designer at the Mashiko-cho Design Festival in Haga District. The designer, who used fluorescent colors in their distinctive designs, unfortunately, I've forgotten their name. I purchased this over three years ago, so it's likely difficult to find now. The cushion features a boldly printed heart-shaped clay figure on suede-like fabric. This clay figure has a heart-shaped face and embodies both male and female symbols, representing the strength and kindness of both genders. It was created with the hope that the owner would become a guardian deity, filled with love and a unique personality. The back is made of cool linen fabric, making it suitable not only as a unique interior item but also as an armrest for a sofa.
