Adidas short socks Set of 3 Black, gray, white Unused, without tags The size is unknown because the tags were cut off and stored... I measured them, and the actual size was about 14 cm (photo 3). They are almost the same size as the socks I have at home, NIKE Cushion Ankle XXS 7c-10c 16cm (4-5 years old), so I've listed them as 16-16.5 cm. Thank you for your understanding.
