Thank you for viewing! These are portable slippers perfect for ceremonies, school visits, and other occasions. They fold in half and can be stored in the included drawstring bag. The size is 25cm when measured with a ruler, but they felt a bit tight on me, and I usually wear 24.5-25cm. Recommended for those with feet 24.5cm or smaller. Please purchase with the understanding that these are stored at home by a private seller and have been inspected.
