They are curved so that they don't leave bumps at the shoulders (unlike practically every other hanger out there). And at only 20¢ per hanger, they are ridiculously cheap. I switched out my whole closet to these and it cost me about $15.
The only downside: what to do with all my old, unwanted hangers. I hated to simply throw them away. I ended up giving them away on the CraigsList free forum.
