This is a replacement for the black 'puck' that comes with a Hopsulator Trio and adapts it for shorter cans (12oz / 375ml). If you've lost yours, or want to keep an extra one in the freezer to ensure you can always keep your beverage extra cold, this is handy!
Filled with a non-toxic, long-lasting freezable gel, it will keep your beer ice-cold until the very last drop.
