Corkcicle swaps out the foam sleeve for a double-walled, stainless-steel design that keeps cans chilled for up to three hours. Using a freezable cooling core, the icy base screws into the bottom of the holder to ensure every sip is cold while preventing unwanted condensation. It's sized to hold the slim 12-ounce cans, making it ideal for most seltzers, craft beers, and specialty cold brews, but also includes an accessory to fit 8.4-ounce slim varieties.
