Are you locking customers out?
Have you tried opening your packaging like a consumer does? I'm a little less dextrous since passing the 50 year mark 3 years ago. Either that or Packaging is getting harder to get into. Consumers want instant gratification. EVEN the time spent looking for a knife can be a major inconvenience.
Oh, and by the way, the Baby Boomers - remember them, the largest segment ever? They need help reading type. So why do the idiots who design packaging put instructions in the smallest san serif type face. Curse these idiots and the idiots who approve their work.
