Stacking burgers has never been easier...less sticky! These 6" x 6" square wax coated sheets are non-stick and easy to use. They allow for an easy transition from creating your burger to its placement on the grill. And if you make more burgers than you can eat, then stack them using the Non-Stick Burger Papers and put them in the freezer for later use. The non-stick sheets will allow you to easily separate the burgers even after they've been frozen.
