They ran out of Season One case files. I have one...I paid way too much for it on eBay.
It had a cardboard set of "hypno glasses", a "One Rabbit, One World" Max election pin, a Ted E. Bear magnet, a postcard from the moon, a copy of Alien Love Triangle Times, and a BoscoTech napkin. Pictures of the contents can be found here
a bit down the page.
