Here's a good (and green) idea. The under layer of Huffco Entrance Mats is recycled rubber from old tires bound for US landfills. The non-skid, dirt-trapping top layer is made from 100% walnut shells.
We love the inventiveness of the gritty nut surface but, this being an outdoor product, we're left with one question...
We worry about critters. Will the walnut shells, even when stuck into rubber, still smell like food?
According to the lone customer review at Buzzillions, our concern is not unfounded. BCW states:
The squirrels have torn up the outer nutshell layer within one week of purchasing the mat.
