Blank Magnetic Neoprene Collapsible Slim 12 oz Can Coolie is an upgrade from foam collapsible (more durable, dense wet suit type material) and is ready to use or for decoration with screen print or vinyl. The coolie measures 3.5″x6.5″ when flat (including 1″ bottom, subtract 1″ for height when in use) and is 3mm (about 1/8″) in thickness. There are 2 seams, one on each side of the item, the seams can be recognized on the exterior of the item by a zig zag stitch up and down. This can cooler fits slim (skinny) 12 oz cans such as Ultra, Truly, White Claw, some brands of energy drinks, also fits beer bottles. The bottom of the item is a 1″ long collapsible “foot” so it is not completely enclosed, it is vented for easy folding/storage. 2 strong magnets on 1 side will hold a full can to metal objects.
