Produced locally by massive industrial machines (no, just kidding! They're handmade), these predatory machine-washable knit sleeves cover all your drinking/tech needs, with everything from "Monster Shark" iGadget holders boasting jagged teeth/button eyes/fins, to a similarly fishy cozy with the can's mouth coming out of the shark's jaws -- ironic, as beers on a rocking boat are more likely to land your can in Jaws.
