This is a set including a pink pelvic belt to support the pelvis, a size M-L maternity panty (front opening) made of 100% cotton, and a nursing bra. I received these at the hospital when I was admitted for childbirth, but they were the wrong size and I didn't use them, so they are new and unopened. The pelvic belt's package has been opened, but it is also unused and new. Would these be suitable for your hospital bag for childbirth?
