Haven't had a chance to install yet but I'm sure they'll work perfectly.  I've been shopping some simple hold backs to match the curtain rod in my son's room for over a year.  I saw some that would have worked "okay" but they were close to $20 which is more than I paid for the curtain rod and just couldn't justify the purchase.  So happy I waited!  These match perfectly and were under $10.  Great find!  I could not be more pleased.
