If you’re an Eastern European, you know what kefir [kuh-FEER] is. If you’re a Russki living in Chicago, you definitely know what Lifeway Kefir is. The Smolyansky family (the people behind Lifeway) have been making this delicious drink for 25 years. And to celebrate this anniversary, they have released the Birthday Cake flavor, accompanied by a custom flash drive in a shape of their signature product. We were the company chosen to fulfill this project.
