I reordered a few days later (when back in stock) and you promptly sent the correct Zauber Tire Link Non-Slip Outdoor Door Mat.  A perfect solution to my need to replace a similar mat that after many years of use in our small studio (Elf Photo) entrance that had failed due to the wire that holds the pieces together.  I highly recommend these cut tire mats, they are very effective  in preventing track in, I use them at both my home and our studio.
