Old Navy beach sandals, 12.5cm. There is a size marking on the inside of the sandals, but I couldn't take a picture of it. Purchased new. The size didn't fit, so I only tried them on, but there is some dirt on the soles and toes. (See photos) I have also listed several discounted items that can be purchased and shipped together. Please consider them as well. If you have any questions, please feel free to let me know in the comments. I will ship via Mercari delivery. Depending on the packaging situation, I may change the shipping method from Rakuraku Mercari to Yuuyu Mercari or vice versa without contacting you. Thank you for your understanding.
