Usually they're not marked at all, just sent via express post in a box with some holes in it. I ship insects and get them shipped to me regularly. Live fish too!Fancy, I don't think I'd like your husbands job... Although, playing with explosives can be fun... I wish we would have had more of that sort of training in the military. It was really cool to build bomb strike simulations for live ammo shooting practices.
I wonder how a package that says "Live Spiders" gets treated in the post office...
