One of the important findings of the consumer market research was that consumers knew very little about the hearing aid batteries they were using on a regular basis. They also could not read the material on the package because the card size was so small. All the information on the traditional cards was in very small print that was impossible for many of these elderly users to read.
The decision was made to go with a much larger card, two and a half times the size of the traditional packaging. This larger card size enabled the designers to use larger fonts to communicate with this elderly crowd , and it enabled them to use a lot of pictures. The pictures were very effective in explaining how the device works. The card included a picture of the device that was about to be inserted into the hearing aid. To enable even more communication, the new package opened up to provide room for printing on four different surfaces.
