An innovator in the trial size arena, Convenience Valet was the first to blister pack OTC medications, supply multi-packs, create color-coded category cards, do drug-fact compliant labeling and provide planograms based on syndicated data.

Since its incorporation in 1955, Mechanical Servants, Inc. has strived for this industry innovation in every aspect. The focus of the business has evolved over the years from mechanical vending machine manufacturing and distribution to traditional retail outlets. In the late 1980s, the company made this shift by changing packaging and offering products in blister packed formats.
