Feel same way as you mate
...but I wonder though, yiou can either insert the Folding disk Holder with Bonus item in the FullSlip, but if you decide to put the Disk with the Steelbook that comes with it, can you fit instead in the FullSlip the Steelbook with the Bonus Items (Basically just switching the fold in holder for the Steel in the FullSlip) ???
I Ask as I saw the unboxing of Godzilla that
@bloodsnake007 posted and it seemed that the FullSlip was much larger in the opening than a regular FullSlip for exemple Nova/Fa/Kimchi Size that fits a steel and the Bonus on its side, the Fullslip on the Japanese Godzilla appeared to be quite Larger
