After our intensive research and testing with multiple types of material we developed a material called PremeLeather. The anti scratch and waterproof capability allows for regular used, even in areas with harsh conditions. The oil resistant and acid proof ability minimizes the worry about the maintenance. PremeLeather is considerably more durable and stronger. On top of all this, we are passionate towards the responsibility of saving our environment and natural resources and are proud to to announce our sponsorship for the World Wildlife Fund. For every AutoPreme floor mat order, we will donate $5 back to the World Wildlife Fund. Learn more at www.worldwildlife.org.
Another reason the metal heel grip is there is to help to help females who wear heels often. This keeps their feet in place and protect the floor mats. There are also rubber nibs covering the heel grip.
*There will be extra AutoPreme clips, is it not necessary to use all of them
