Input:
I used to own a dish like this which had both a glass and plastic lid.  I searched for a while for a new one. On the Amazon page, underneath the product title, it states "Glass and plastic lids make cooking, serving, and storing easy and convenient", so naturally I thought I had ordered a product that came with both a plastic and glass lid.  It only came with a glass lid.  I find the corningware design very unattractive and am not pleased that I won this product. The product arrived without a packing slip, so I am unsure of my options for return.
