Can we just say, "this works!"? Seriously, we have not experienced one solicitor interruption since placing this on our front door. The reason we designed it to fit VistaPrint's small car magnets is that a lot of front doors are steel and this will magnetize to the door. However, there are options we will provide for those who do not have a magnetized door. Either way, get this printed, it does not cost much and is SO worth it!!
