I bought the Stay-Chill Standard Can Cooler in Peony and it does exactly what it promises. Unscrew the top, slip in a 12 oz. can, and the double-walled vacuum insulation keeps my seltzer cold much longer than a plain koozie. The ergonomic grip and non-skid base are nice touches, and the screw top lid stays secure. Stainless steel and plastic feel solid. Just remember it's hand wash only. The peony color is a fun bonus.
