Product review (5 stars): Cut to size for gas oven
I have a gas range and the oven has 2 vents at the bottom where the heat is emitted.  I cut these to size to make sure the vents were exposed.  Cutting them was no problem and it lays perfectly flat at the bottom.  This products arrived just in time for a cheesy pizza.  Easy to clean and since it is a 3 pack I know I have backup in case anything happens.
