This item was included in a SLY New Year's lucky bag about two years ago. The size doesn't fit, so I haven't even tried them on. There was no original box, only a thin white shoe bag and a SLY bag. Please check the third image for details on the price, materials, etc. The size is listed as 23.5cm, but if you use a half-size insole sold at Daiso, they can also fit a 23cm foot. The color is a clear beige, and I think you can wear them year-round except for summer. Although they are new, they have been stored at home for a while, so please consider this before purchasing.
