These are baseball socks. One pair is Tabio 5-finger socks, size M. The other pair doesn't have the manufacturer name or size listed, but is about the same size as the Tabio socks. The Tabio socks have holes in the seams on the top of the toes and the inner ankles, and also have some dirt. The other pair hasn't been used as much and doesn't have any holes. They will be shipped in a plastic bag and an envelope.
