These affordable cutting mats are designed for use with rotary blades and hobby knives and have excellent lay-flat properties. Ideal for all sorts of tables, benches, counters, and work spaces. This cutting mat reduces the dulling effect of slicing on a flat surface while reducing the chance of unexpected sideways slippage. Please note that the grid leaves a two inch wide, unprinted perimeter. For example, 48" x 96" cutting mat has a grid size of 44" x 92".
