Sooooo... You've got a two camera shoot.  

And you'll be working outside in the bright sunshine...  

Or maybe inside of a studio with a whole mess of lights...  

Or perhaps you'll be shooting in the rain...

Then you're gonna' need a two pack of Nasty Flags.

Note: Nasty Flags are made from super-tough ABS plastic (the same stuff that LEGOs™ are made from), and each flag is individually machined in Portland, Oregon.

Details: The flags themselves are approximately 9 inches by 5.5 inches.  The flex-arm coming off of the clamp is approximately 16 inches long.
