Thank you for viewing. I purchased this item because it can be used from newborns, but I never had the opportunity to use it, so it has been stored at home unused. It has been home-cleaned. Made with skin-friendly organic materials, safe for delicate baby skin ♡ Weight: 720g Materials: Fabric/Cotton, Belt Padding/Polyethylene 62%, Polyurethane 38% Usage Period: From 3.2kg (newborn) to 20kg This is a perfect item for the coming season. Please consider it!
