Ralph Lauren black ballet flats with ribbons, perfect for both formal and casual occasions. - Brand: POLO - Color: Black - Style: Ballet flats - Material: Synthetic leather - Design: With ribbon Thank you for viewing. I purchased these without checking the size, and when my daughter tried them on at home, they were already too small. They felt a little smaller than 21cm. They have never been worn outside. There is a round, embossed-like mark just below the ribbon on the left shoe (see photo 3). I would like to sell them to someone who needs them. There is no box.
