France National Flag (3' x 5', 100% Polyester) by Urban Boundaries. $5.99. 3' x 5'. 100% Polyester. Perfect for your dorm room, bedroom, or casual outdoor use. We do not recommend the 100% Polyester Flags for continued (everyday, all day) use outdoors. They are great to celebrate specific events, but are not created to sustain a 365 day, all weather hanging. All flags have the edges sewn down and come with two metal grommets for easy display.
