Not rigid, stains easily
I used these once, just to serve spaghetti.  The sauce left a bad stain that I couldn't remove, even after washing  three times.  See the photos.  The plates are very light weight, but they are not rigid.  They are sturdy enough, but you should be aware that the plates are flexible and can bend a bit, so stuff can spill over the edges if the plate is too full.  At $2 a plate, that makes these pretty pricey disposable plates.
