Compression socks with a diamond pattern. Each pattern is different. I bought these years ago and never wore them, so they've been sitting unused. I don't think I'll wear them in the future, so I'm selling them. There is no outer packaging. They were stored in a zip-lock bag. For those who understand. I believe the material is nylon. #CompressionSocks #Black #SchoolSocks I am also listing these on other sites. If they sell there first, I will delete this listing. Thank you for your understanding.
