25 count pack of disposable cutting boards. Disposable cutting boards are really helpful to avoid cross-contamination. They are made of a high quality coated food grade paper. They have a large cutting area of 18 X 24 inches, but can be cut to size for smaller jobs.
There are measurements along the edges for cutting your food to size. There's also a 9 inches x 9 inches square in the center, especially nice for sizing perfect proportions in BBQ competitions.
