Petit main diaper pouch. I received another one as a gift, so I haven't used this one. Although it doesn't have a tag, I have never used it. It has an expandable zipper, so you can change the size. It's convenient for carrying around things like wet wipes and spare diapers all in one place. It comes with a strap for easy carrying. ■ Outer fabric: 100% cotton Filling: 100% polyester Lining: 100% polyester
