This long post-its are not mainly because of the lines, particularly well suited for shopping lists (there are normal post-its usually just a little too small) and adhere fine on the inside of my pocket (s), so I the Einfauszettel must seek, but easy find (where I stuck it in his pocket).
Alternatively, I use them as a simple notepads on the go. The adhesive surface is stuck so that its post-a very good block replacement give and then you can take apart and sort the notes. That's nice and practical as these frayed edges correctly notepads in which the most varied (no longer current) accumulate information over time.
