Five feet eight inches of foil spelling out “Happy 100th Birthday,” 7.75 inches tall. Foil catches light the way paper never does, which matters when the decoration doubles as the photo backdrop for a once-a-century picture. Some assembly is required, and it belongs indoors or under shelter outdoors, since foil and weather do not mix. Made in the USA.

Sold by the package (1 streamer) or by the case (12 streamers).
