These thick curtains gently darken the room and provide privacy by preventing people outside from seeing into the room. Not a full blackout. The eyelet heading allows you to hang the curtains directly on a curtain rod. Effective at keeping out both drafts in the winter and heat in the summer. Package contains one pair (two panels). I have two packages available - please see the other listing if you would like to purchase a second pair (four panels). NEW IN SEALED PACKAGE
