The Happier Place Slim can coolers fit 12 oz slim cans (for hard seltzers, cocktails, hard ciders, energy drinks, skinny La Croix and Red Bull, some beers, etc.) and 8 – 9 oz. short cans (for wine, wine spritzers, coffee drinks, Perrier, etc.). They also feature motivating slogans to inspire to be happier. Cheers!
