So much more than your average koozie. These pieces of art are handmade right here in Portland by Maine Leather Company. Each features a hand-stitched state of Maine with "Allagash" burned into the leather. Riveted closure on back, one rivet featuring a teeny-tiny state of Maine! Please note-- they do not open. The rivets permanently secure the koozie. Also, please note-- these fit Allagash bottles, and standard aluminum cans. They are not made to fit the common, thinner beer bottles that are out there. One size. Maine made.
