Size: 13.5 cm. Worn twice indoors for a short time at a kindergarten orientation. They have never been worn outside, so they are in good condition and clean. I'm selling them because my child will soon outgrow them. There is a small stain on the toe of the left shoe (see photo 7). Please refrain from purchasing if you are concerned. I originally purchased them without a box, so I will send them without a box. Thank you for your understanding.
