Mr. Moderator can you copy this post or move it later on in the right thread? Thanks! Its a plastic book with the gels in it. The case is huge! The bottom is a flash diffuser dome and gel holder storage. gel holder Ohhhhhhh Pretttttyyyyyyy! What i love is i sold my SU-400 for the pocket wizards, i forced myself to think about the flash and how to use light manually, but i did love the lighting i got messing around with the iTTL. And the SU-800 looked like this but this screen is much better. Size Comparison. This thing is BIG!
