CLEARANCE! The reason this car flag is only $1 is because they have been in the warehouse since 9/11 and the plastic post is very brittle. The opening to attach on the car window has gotten smaller over the years and is tough to clip on. These can mostly be used to hand hold them for parades or for give aways. The flags themselves are great. You can take flags off and put on different posts if you want. This World Trade Center Commemorative Car flag is a ONE-ply car-window flag, and is made with polyester fabric. This 10" by 17" car flag is on a 17" flexible plastic pole that attaches to the car window - no tools needed (patent design #454590). This car flag is for display only not recommended for moving vehicles. Don't be fooled, this fabric is very good. The wind goes through it and not against it so it does last if you take care of it.
