This is a baby sleep sack from go sprout. Size: 60-70cm Outer fabric: 100% cotton Lining/Filling: 100% polyester As shown in the 6th photo, the inside is made of thick, sturdy towel fabric. It's colorful and very cute ♡ Even for babies who roll over, you can rest assured that they won't kick off the covers. It was stored at home without being worn much. There are no noticeable stains or fraying, but please understand that this is a used item. It will be compressed for shipping. There may be creases from folding. Thank you for your understanding.
