Another name for them is "shelf bra". I did a search for that in Google images and eBay and found a lot of things. Because of it's excellent search system EBay can be a great place to find things like this if you learn to be a careful shopper and avoid problem sellers. Also, I avoid the many listings from sellers that come directly from China. I've found those often take a long time to ship and have gotten defective merchandise that way. I'm in the US and sellers inside the country have to be more careful, I think.
