I purchased this to prevent pain from an episiotomy after childbirth, but I didn't use it because I had a C-section. I brought it to the hospital and tried sitting on it. Since then, it has been unused and shows no signs of wear. I also recommend it for those who have had surgery or are suffering from hemorrhoid pain. Please see the photos from the fourth image onwards for the size, etc. It's a high-quality made-in-Japan product that I purchased for about ¥8,000 at the time. It has been stored at home, so please refrain from purchasing if you are concerned. I'm not considering lowering the price because shipping will be quite expensive, but it's a good quality item that will last a long time.
