I received these items when I went to a hot spring at the end of last year. There are two pairs of socks. I wore one pair that day and have home-laundered them. There are no noticeable stains. The other pair is unopened. Also, the body towel is unopened. I'm not sure of the exact size, but it's about half the size of a regular towel. The socks are made of a soft material that kept my feet warm. They were comfortable to wear after the bath. How about these for your hot spring trip?
