Genustech Side Flags for Production Matte Box

The Production Matte Box's front tray shields the lens from light coming from above, but a source off to either side can still reach the glass and cause flare. This pair of side flags closes that gap, mounting to the matte box to cut light from the left and right independently of the top flag.

They are sized specifically for the GPMB-Kit Production Matte Box and install without tools.
