Use DUCT TAPE!
Size: 7''x3''
I actually ordered the window signs for cars. Even though it shows different, I got what I ordered. The problem comes in where it shows where they just stick in the window. WELL, THEY DON'T STAY FOR LONG. I drive for Lyft and Uber. I want those signs and need them to stay where I put them. The stuff they send with the signs is junk. USE DUCT TAPE AND BE DONE!
