F FlammiFlammi Women's No Show Liner Socks Non Slip Cotton Bottom Socks for Sneaker Lofer

How many in a pack?

I used to love these but my husband got me some for Christmas and there was a packing and quality problem. Did company change quality?

Do you actually get 4 pairs?

Are these like hosiery? Because I need them to be really thin for some tight shoes I have.
