Asahi SUPER DRY EXTRA COLD This item was obtained through a 2010 campaign. I had two sets, and this one has been kept unused at home. I haven't confirmed whether it works properly. It's a new, unused item, but it has been stored for many years, so please understand this before purchasing. Includes instruction manual and quick operation guide. ~From the website~ The "Extra Cold Cooler" cools cans of Asahi Super Dry (500ml, 350ml) that have been refrigerated, using a dedicated cylinder filled with a specific concentration of saltwater that has been frozen for at least a day. The can and cylinder are set inside the device, and the can and beer are cooled to below freezing by rotating together. Insert the can into the dedicated cylinder holes, which hold four cylinders, and rotate. It takes about 5 minutes for a 500ml can and about 3 minutes for a 350ml can to cool to a temperature between -2°C and 0°C. ⭐︎Please read my profile⭐︎
