The branding look and feel of the Avenir graphic scheme was already established. The primary responsibilities Marcus brought to the Avenir product line packaging consisted of engineering unique structual designs to help their product stand out from the competition. This one-of-a-kind, interlocking structural design consisted of a single sheet of folded paperboard and requires no glue or twist ties.
