I know this already, and I know probably a lot of people already know this too, that the new cardbacks are flimsier/flexible than the older ones, but I find them to be actually quite an improvement over the older, sturdier cardbacks.
I was at a store holding a Cloud Car Pilot, and I accidentally dropped it (typical me

) - but, instead of the corner of the packaging fringing and bending and creasing up, the cardback bent only a little bit (without any of those annoying, thin white creases show up), and I was able to re-straighten it. I'm not recommending dropping your MOC-packaging figures (not that anyone would actually do it), but if they were to fall, the flimsier pakaging would actually save it from being severely damaged.
