When they say "non-slip" they mean "non-slip!"  I have a long, narrow closet that makes it's difficult to look through my clothes for a specific item without everything sliding off the old wire hangers & ending up on the floor.  Not anymore!!  These hangers keep pants from bunching up & tops & dresses hanging flat, so they don't need ironing.  It does take a few more seconds to hang things on them because of their grip, but I am VERY PLEASED with these hangers!!
