My daughter wore these five times. They're in relatively good condition, but there are faint scratches on the 13th and 14th photos if you look closely. I think they're fine to wear. Regarding the size, it's not written on the shoes, but my daughter usually wears 20cm and couldn't wear these anymore. She wore them when she was wearing 18cm and 19cm sizes, so they should be a good fit for someone who wears 18cm to 19cm. I apologize that I can't specify the exact size, but I'm offering them at a lower price as a result. Please understand. I will ship them via Yu-Pack or Takkyubin. #SnowBoots #HeartPattern #Girls #18cm #19cm
