These are mobile slippers from Belle Maison's Monthly Club. The slippers fold in half and can be carried in a drawstring bag. Size: 22.5-24 cm Material: I believe it's polyester. The drawstring bag is non-woven fabric. I have stored them after taking them out of the outer bag, so the outer bag is not included. There is a crease in the middle of the slippers from being folded. Thank you.
