Purchased on Rakuten for 2,980 yen before childbirth. However, I didn't experience any perineal pain with my first and second children, so I haven't used it. It's a product called ReLarela. It has been stored at home, so please refrain from purchasing if you are concerned. A black donut cushion that provides a comfortable sitting experience. - Color: Black - Zipper: Yes - Shape: Donut cushion Thank you for looking.
