I bought these to make it easier to spot my child at the sports day. They're also perfect for casual styles, Halloween, Christmas, girls' dance, group dance costumes, and team outfits. I bought a set of two and only need one, so I'm selling the other. They are new and unused, but I have opened the package and taken one out. Please understand that these have been stored at home before considering a purchase. 【Material Composition】 Cotton, Polyester 【Care Instructions】 Machine Wash 【Pattern】 Striped 【Size】 Free Size: Total length approximately 38cm ※ Heel-less design ※ Estimated age: 3-12 years old ※ Depending on height, the top of the socks may or may not go over the knee.
