This lot includes 3 pre owned newborn sleep sacks. They are all the same size but have different closures. I have included pictures. One of them is a zipper closure and it wraps around the baby as a swaddle. The second one is a snap button closure and it wraps around the baby as a swaddle too. The third one is also a zipper closure but when it wraps around the baby, it uses Velcro as a second layer of security. There is a tiny hole in one of the sleep sacks but it is not very noticeable and does not affect the functionality of the item. These sleep sacks are made to help new and expecting moms to have peace of mind when putting baby to sleep on their back. It helps with easily swaddling and helping baby sleep on their back.
