The size is listed as 23.5cm, but when I, who usually wear 23.5cm to 24cm, tried them on, they were a little big. I haven't worn them outside. I only tried them on at home. I will ship via post, so I will use simple packaging and compress the item. Thank you for your understanding. Please refrain from bidding if you are nervous or concerned about minor details, as this item is stored at a private residence. There may be minor scratches that I have overlooked. Thank you for viewing. Color: White
