Our Coin Rubber Mats are made of natural rubber and provide years of trouble-free service. This is a top-quality natural rubber, not a cheap imitation. It features a new anti-slip ribbed surface, is non-porous, non-absorbent, and urine-proof. The matting is easy to clean and disinfect, will not swell, curl, or lift, and is dust, spore, smell & allergy-free for both humans and animals. It offers insulation from cold and is slip-resistant when wet, making it a tough and long-lasting solution.
