Product review (5 stars): Multi-purpose Silicone Cover- bake, microwave or store it!
This product is used primarily as a cover for a 13x9 rectangular bake pan.  I really welcome the bakeware silicone cover I recently purchased from Amazon. Most 13x9 bake pans have no covers or poorly sealed covers.  As a result, baked goods turn stale quickly.  This product however, is made of high quality silicone and creates a tight seal on a metal 13x9 cake pan.  My cake has lasted over a week in the refrigerator since I began using it.
I also enjoy the versatility of the rectangular cover since it has other uses as well, such as covering a baking lasagna casserole in the oven to keep the cheese on top from getting too brown.. It also fits some of my rectangular ceramic baking pans as well that are slightly smaller. It can also be used as an oven splatter guard over a square roasting pan, to keep fatty meats [such as chicken pieces] from splattering in the oven. It is therefore great for oven, stove or microwave use, as well as a sealed storage cover.  As I use it more, I am sure I will find other uses for it.  Definitely a great high quality multi-purpose kitchen tool worth having!
