Holy crow, you see this sexy hooch-hauler? Cold-rolled steel, finished in the perfect Foundry black powdercoat. Its tool-styled finished cap was crafted with internal threads for a smooth lip land with every swig. Picking up what we’re putting down? No? That’s cool, all we’re saying is that that this bad Larry is a jaw-dropper. Careful of sticky fingers if you pass it around.
