I get emails all the time through VistaPrint for free offers. One of their items is a window decal that is 4.8" x 4.8". You could get a couple of BIT tags on there and then just trim it up when you get it. I may try that with the BIT tag that I have for the SUV. The one I have currently is just laminated and I don't have a way to permanently mount it yet. Just another idea.
