Each pair of socks came on a piece of cardboard. I noticed some dark spots through one of the socks when I took them out of the bag. I pulled the sock back to see why there were dark spots and found black dusty stuff on the cardboard and on the socks that were touching the cardboard. The cardboard also appeared to have been wet at some point as it was rippled and stained. It was dry when I received it, but growing mold, I believe. The bag these socks came in was not sealed, either. Grossed out.
