I bought two mats from Frontline early in 2014, the bags that they came in slowly started to tear. I contacted Frontline to see if can purchase two more to replace my old ones with the newer design.
See the results! The new cases make the purchase of Frontline mats for new buyers that are looking for a high quality mat and carry option this could be for you. A bit more expensive than other options out there and again it comes down to what your needs are.
