Purchased on Rakuten in 2023. I bought these for my daughter. The black ones were worn about 2-3 times, and the brown ones were never used, as she outgrew them. The size is M, which is 23.0cm-23.5cm. They are low-heeled, with a heel height of 4.1cm from the floor. There are no noticeable stains or scratches. How about them for the summer? Please understand that these are used items. Thank you.
