The creators of the Rogue FlashBender have created a 3.5-ounce package that offers the performance of a 16-, 25, and 45-degree honeycomb grid for your flash.

The newest product from Expo Imaging, who you probably know from the wacky-but-useful Rogue FlashBender, combines three variations into a single package.
