Thank you for viewing. Crew-length school socks, set of 7 pairs. I'm selling these because the length doesn't meet school regulations anymore. The right 3 pairs were purchased at Aeon, but I no longer have the outer packaging, so I don't know the manufacturer. The knitting is quite sturdy. *The rightmost pair has been worn once. Washed. ----The following are the specifications for the left 4 pairs. Easy-to-use crew length ・Plain, simple crew-length socks perfect for the park or school. ・Dark-colored soles to make dirt less noticeable. ―Material― ・Antibacterial and odor-resistant processing to eliminate odors. ―Features― ・Name space on the inside of the opening.
