This 4-pack of insulated wine chiller buckets uses double-layer stainless steel to help isolate the temperature inside and outside each bucket. The design keeps wine and other beverages at the best temperature and keeps them cold for hours without requiring ice cubes. Made with 304 stainless steel, each chiller is sturdy, durable, and provides high-efficiency, continuous insulation while helping prevent rust and corrosion. The buckets accommodate wine, champagne, juice, and other beverages, with a fit for multiple bottle sizes. For convenient serving, place a refrigerated bottle directly inside instead of handling excessive ice and the water droplets it creates. The chillers are easy to clean and suitable for food and drink use.
