Does the club at least ship its figures in those resealable cardbacks that I've seen customizers use?
You mean like the SDCC clamshells? Nope. But funny enough, dorkside throws in one of those for free, and at a TON less than the Club.
If it's some other method to be able to pull the figure out and re-card him? Nope, they're just like any 25th card you'd find. The earlier ones like Dial-Tone and Dr. Venom were on a shittier quality car stock, but the more recent ones (FSS, Footloose, etc.) are of equal quality to the SDCC/25th cards.
Or at least, they SHOULD be. The FSS2 figures come with so much shit crammed into their bubbles that they had to go with a wider one, which I wonder isn't part of the bubbling/stamping issue. It's almost like the wide bubbles are too much for the press machine to handle, so it fucks up a good portion of them. Or they're running them too fast or too hot, and it's melting the plastic more than just heating it up to adhere it to the cardbacks.
Either way, they have more issues than simply cramming them into boxes. The ink's been coming off on some of them due to overheating, along with the aforementioned bubble melting.
BLAME CHINA!
(Actually, I'd assume it IS actually China's fault for once, since they're the ones making and shipping these fuckers out.)
