This is an American Greetings Strawberry Shortcake Baby Sling Carrier; it is adorable; there is just one manufacturer's tag on it; I am assuming it is machine washable and that it is cotton; it has a metal ring; I do not know size; it is preowned by someone other than myself; along one edge there is a light yellowish color (hard to see in photo), I do not know what it is; will need to be washed before use; overall it is in great condition; please, prior to purchasing, if you wish to see additional photos or have any questions, just email me and I will answer you as soon as possible - THANK YOU FOR LOOKING!
