research Ideas for the booklet

I was looking at the possibility of the booklet being more than is an addon. What if it could become part of the package. I had in mind a type of booklet that could become part of the label and I finally found an example of what I meant.

This label turns into a booklet by securing the additional pages to the label with a sticky back plastic covering. This does look easy enough to recreate, however, finding space on the label could prove difficult. The label may have to be reprinted.

i realise it isn't the most appealing piece of design but looking at the mechanics, it works.
