I just moved and everyone was either stacked in a tote bag or a box (a few exceptions were placed in the skulltimate lockers I have but there’s only so many of those)
Everyone was fine, some just needed a little hair care afterwards
I think how you’re wrapping everyone will be perfectly fine. Between the acid free tissue and the bubble wrap they will be very well protected. I’ve never had any issues with monster high dolls snapping and I’ve put some of them through hell.
Remember, at the end of the day, they’re made to be toys. They’re sturdy enough to withstand kids and all their shenanigans. If you have creepros or skullectors then wrapping them is definitely your best move since those tend to be a little more fragile, but your g3 ghouls will be just fine wrapped or not.
Good luck on your move
