Set of 2 NWT socks by Sockwell, 20-30 mm/Hg firm compression in M/L. One pair is black floral called Fauna, the other is a style called Pulse in Cornflower blue. I have worn compression for a few years and I'm particular about it. There is another listing of two open pairs. I think these run a touch larger. Please let me know if you have questions.
