Vampire Squid Cards has just announced Crabs Adjust Humidity: Omniclaw Edition, a boxed set of all their previous Crabs Against Humidity releases. The box contains all 560 cards from Volumes One through Five of the unofficial Cards Against Humanity expansions. There’s even space in the box to hold future expansions.
I personally have never used any of the Crabs Against Humidity sets, but this may be a reason to give them a shot.
You can snag the Omniclaw Edition for $49.95.
