These are ballerina flats made of lambskin, patent leather, and calfskin. Size is 36, which I believe is approximately 23cm to 23.3cm. They were a bit small for me, as I have slightly wide feet and usually wear 23.5cm. I purchased these a few years ago at Hankyu Department Store. I've tried wearing them a few times, but the size just doesn't work for me, so I'm putting them up for sale. There are no noticeable scratches, but I have worn them a few times, and there may be some minor imperfections I've missed. Please consider them as a pre-owned item. The soles have not been reinforced. The box has some minor scratches. Regarding the purchase receipt, I can provide a copy with the price and personal information blacked out if you would like it. Please let me know if you need it. I'm a little hesitant to sell these, so I may remove the listing without notice. - Brand: CHANEL - Color: Black - Design: Ballet Flats - Accessories: Box, dust bag Thank you for looking.
