We are very pleased that you are satisfied. We are happy to accept your design suggestions. The so-called heel mat you call is not intended for the car, but as a base for your glass, remote control or other objects! From soon on there will be stickers there that mark the gifts as samples. The size has now also been changed to round and square! We are happy when our customer appreciates the quality. Especially with this mat, where the production is much more complicated due to the 2 cutouts, we are looking forward to suggestions that would perhaps simplify the production. Kind regards Cpucarpart.com
