Thank you for viewing! This is Mizuno's "Yura Yura Cushion." It's an air cushion product designed to stabilize the pelvis and support core training and posture improvement when used while sitting. Just by sitting while watching TV or using a computer, you can shape up and train your core muscles. It stabilizes bones and the spine in the correct position, creating beautiful posture. It has a two-layer air balance structure, and when not in use, you can deflate it for storage, so it won't take up space in your room. It's also okay to carry it when traveling. Material: Nylon, PU Size (approx.): 33cm diameter, 16cm height ⭐︎ I am also selling other items #parismith Immediate purchase OK Thank you. #Mizuno #MIZUNO #mizuno #cushion #lowerbackpain #core #sports
