The hard plastic case was robust enough for cramming into a suitcase without breaking any of the glass vials and bottles inside it. These cases were sold OTC in pharmacies. There were two sizes. Sales started in 1964. The examples of both the larger one and smaller one on this page were made in 1964. The empty vial was intentional, allowing for a number of tablets to be dispensed from the case to a family member. From the letter below we know that travel cases were given to new shareholders.
