I ordered these larger sized curtain rings because I like the look of a longer curtain panel that sweeps the floor.  My curtain rods are placed high above my windows.  I also wanted to create a casual look with my rod pocket style drapes, not so formal.  They are easy to clip on to fabric and hold substantial weight as my panels are lined, weighted, and heavy!  The curtain rings are of high quality and the black colored metal (so far) is scratch resistant.  I am very pleased with my purchase.
