This 5½" sq. thick black felt pad provides cushioning under paper and protects the work surface when perforating map outlines, geometric shapes, or artwork.
It is ¼" thick and virtually impossible to penetrate!
The quality of the pad itself is great. The size simply didn't work for us. Punch pinning with a 4 year old I think works best with the large pad no matter what the size of the paper with which you are working. I wish I had ordered two large pads instead of one of each.
