well, my first anniversary set (2 skull bees) came in boxes,
and my 2nd anniversary set (ring set) came with the ring, two figures (one bee, one brain) and a t-shirt. [this all came in half a box with a protective plastic covering]
i have a grey obake that came with tiny jp men's undies and a secret base can in blue with yellow lettering.
and i know other figures are supposed to come in pringles style cans. I have one, but it was pretty random! and it also had a... AHEM... condom in it!! a funny gift from the JP seller i'm assuming.
oh yeah, the translucent yellow skullbee kit also comes in a sweet little box.
that's all i really know "for sure" haha... but there is a lot of stuff going on out there. I'm guessing someone like Ramos could tell you best.
