Ferrari uses a Nappa (Smooth) Black material for it's dashboards.  As a contrast offering, we also carry the Cuoio and Beige color cases in Nappa material.  We carry this in the older EZ-Pass, pre 2012 square style transponder, as well as the newer I-Pass, post 2012 round shaped transponder.  Please see below for pictures of the two different types of transponders as we have seen the newer I-Pass also called the EZ-Pass in some states.  The square one is the one we call the EZ-Pass (second to last picture) while the second is the I-Pass (last picture). 

These cases are for the following states: DE, IL, IN, KY, ME, MD, MA, NH, NJ, NY, NC, OH, PA, RI, VA, WV.

Our cases attach to the EZ-Pass and I-Pass using two straps using the Velcro hook and loop ends, see picture two. As you can see from the second picture, the attaching straps to the transponder will not interfere with the reattachment of the transponder with the cover back on your windshield. The covers are also designed to not interfere with the signal with the reader above the toll road. They also resist fading in direct sunlight.

This is available for sale in both the EZ-Pass and I-Pass in Black Nappa, Beige Nappa and Cuoio Nappa.
