These are the limited edition Alien Xenomorph tiki mugs available from Mondo starting right now (like they just started this hour go get one if you're interested) and for the next 72 hours (previously: their Gremlin tiki mugs). You can get the blue, black, and green ones (green one limited to 200 pieces, UPDATE: green is already sold out) for $28 - $42. The brown and bone colored versions will be Alamo Drafthouse and event exclusive pieces. They're perfect for drinking tiki drinks like Ripley Rum Runners, Alien Bloods and Game Over Mans. I love tiki drinks. Whenever I have one I can close my eyes and pretend I'm on a tropical beach somewhere and not in my crappy apartment and-- shit, is that a cockroach? *closes eyes* I'll pretend it's a crab.
Keep going for closeups.
Thanks to Greg C, who agrees they should all come with complementary krazy straws.
