It was a gift, but the size didn't fit, so I only wore them outside once. Since then, they have been stored at home. They are 12.0cm, but they are quite large, about the same size as 13.0cm shoes! *Please refrain from purchasing if you are sensitive. Please only purchase if you understand that these are amateur judgments, stored at home, and used items. Also, to reduce shipping costs, thick items will be compressed. Please only purchase if you understand. Feel free to ask any questions ♪
