I purchased this for postpartum use, but I didn't use it because I had a C-section. The package has been opened once. Purchase price: ¥5,280 Color: Black (PVC leather) The following is the official description: Achieves the same specifications as those used in hospitals! For hemorrhoids, postpartum, or after surgery when sitting is too painful... Using a U-shaped cushion prevents the affected area from touching the seat, eliminating pain. It's resistant to flattening and has a thick cushion that won't collapse even after long use, so you don't have to worry about it. It's useful when you don't want to put pressure on the affected area, such as after hemorrhoid surgery! Many men also use it!
