Beer! The drink of the Gods and everyone else. Like Homer put it: Beer is the cause of, and solution to, all of life’s problems! The only thing worse that warm beer is the beer that has been left open too long. Here is the easy solution to second problem: Beer Silicone Rubber Bottle Caps. They are durable, stretchy molded beer bottle cap charms that will keep your beer fresh after opening. Great for any beer lover or home brewers,who can now keep their beer bottles clean and sterile before bottling with these caps.
