Levenger designs many of its products, with approximately 75% of its product line being proprietary. The company describes itself as a champion of Slow Tech. One example of the mix of old and new technologies, or dual technologies, is the company’s Shirt Pocket Briefcase. The product was introduced in 1992. Levenger is still selling variations of it in 2013, including one with a pocket for holding a smartphone. Levenger also operates stores in Chicago, Boston, and Tysons Corner, Virginia.
