This is a jointly developed product by Akachan Honpo and Inujirushi Honpo. It can be used for both cesarean sections and natural births, so I purchased several as part of my childbirth preparation, but I didn't have a chance to use this one, so it's new, unused, and unopened. M-L size Set of 2, black and border Retail price: 1,980 yen Thank you for looking!
