Review on 🟢 OLFA 9881 RM-SG 18x24-Inch Self-Healing Double-Sided Rotary Mat in Green by Joe Clayton

I have a smaller pedestal on my desk for small projects. I have these larger ones for big projects in my workshop. I like two sides with different colors. I appreciate the ruler's markings, but sometimes I carried a metric one with me (perhaps on the back). It will warp a bit if you try to store it vertically, but it will straighten up again after about a day on a flat surface.
