No refrigeration required! Our variety pack offers all three of our delicious flavors, which are all pretty darn chocolatey and can be shamelessly chugged. We like to start the day with an Espresso, sip a Classic as a hold-me-over until dinner, and put back a Dark as a nightcap, but hey - to each their own. Using only natural ingredients and milk sourced from family-owned farms, our milk offers 20g protein, 0g added sugar, and electrolytes. Unit height: 6.2. Unit width: 2.3. Unit depth: 2.3.
