From the department of small design miracles: I bought a humidifier and the instructions for set-up were on the inside of the box lid.
I didn't have to hunt for the right page in a manual. The instructions were printed in identically sized picture boxes so it was super easy to understand. In fact there were no almost no words, no multiple languages. The only thing better would be no instructions at all.
Why don't more companies use existing packaging to talk to their customers instead of wasting paper printing more things we throw away?
