Product review (1 stars): I would not buy again
They arrived folded up in a little envelope which made them crumple up and bend.  They did not offer any protection and they are unattractive against the stove.  I would not purchase this item again, nor would I recommend this item.  I tried to wash them in them in the dishwasher and they completely warped.  I don't see how they are heat resistant. Not even worth trying to use, I just tossed them in the garbage.
