I had tagged someone’s homemade KillerBunnies case, but it seemed like it was beyond what was reasonable to do, and not reasonable in price. MARK did some web searching and Problem Solved for $13. More than enough room for the 600+ cards that we now have.
If I print this and pin it to the outside of your house, it will indeed bear a sign that says “Dead Bunny Storage”.
That said, I’ll try not to shoot any bunnies in the back of my car when I come to visit you.
