I posted about my product Photography cocoon not too long ago, but these cubes are much more portable than a cocoon design. In fact, they fold flat so traveling with them is a breeze. If you're not on the Calumet mailing list, I just got this in my email. PortaCubes are now on sale with savings of up to $21.00 dollars off normal retail price (or 30%). Three different versions of the PortaCube is based on size, starting as little as $22.00 dollars for the 16 x 16 version. These are an exclusive item from Calumet, but you can grab them through Amazon below. Have fun with those product shots.
