New Children Mid-Calf Crew Socks white Size 5-10

New Children size socks states 6-8 size for children's feet 5-10. Socks were found in the back of the closet and are have stains from dirt. I did not take out of packaging to wash them. I am unsure if stains will wash out. One pack has four pairs (8) socks. I have two packs available & I will sell together for price.
