Ice-cold drinks come in different shapes and sizes, and the Load-and-Lock™ Slim Can Gasket helps diversify your Colster. It's an easy add-on to your Colster®, prepared to lock in slim bottles and cans. Just twist off the standard gasket on your Colster, drop in your slim can, and screw the new gasket in its place. Like the Colster itself, the Slim Can Gasket is dishwasher safe.
