These are just what I was looking for.  I have curtains that are on a pull track system and require sharp needle like hooks.  I didn't want to put those sharp hooks into my new curtains and found these instead.  So happy they work great and fit perfect into my track in place of the clips.  I gave them 4 stars because when they arrived they were all together in a plastic bag.  Some of them were stuck together and took me awhile to untangle them.  Besides how they were packaged they are great..thanks WayFair!
