Los Angeles customs doesn't seem to give a fuck. They've never caused problems for me beyond my package sitting there for a couple days.
I've even ordered shipments of prescription drugs where the seller plainly and honestly labeled what was inside right on the box.
If there was one of each other figure left then they actually bought every figure except the two women. (MCU Thor and MCU Loki are double-packed.)
What a weirdo.
Or a non MCU collector who is getting the SDCC boxset. Both sets of Movie Thor/Loki were still there.
Hopefully Ares isn't too hard to find. I ended up 2 pieces short of the BAF last time. Never got that Crossbones or Guardian.
