The open-weave design allows for air circulation. Place under electronics, between plates, or anywhere a degree of cushioning is needed. It can also be cut to make attractive and practical placemats, coasters, and tray liners. In addition to its protective qualities, it prevents slipping and sliding of the items placed on them.
This lays flat without adhesive, so no added fumes to breath and no added food for silverfish. And, its PVC free, made of polyethylene, a healthier plastic. Its also ribbed so air circulates under stuff preventing mold, mildew, and odors.
