Where can I find a retractable banner that is not on a stand?

the width being between 5 and 9 inches and the length of the material/fabric between 35 and 40 inches.
i don’t need anything fancy. just something matching those lengths that can retract… similar to a tape measure or overhead projector screen
i don’t care what is on it, I’ll be putting my own pictures on it. I’m using this for a skit
