First time I saw the movie "Godzilla" (1998), I just impressed not on the special effect or the storyline, but with its headline first: Size does matter.
Godzilla is a 1998 American science fiction film directed by Roland Emmerich and starring Matthew Broderick, Jean Reno, Maria Pitillo, Hank Azaria, Michael Lerner and Kevin Dunn. It is the American movie remake of the Japanese 1954 film Godzilla which began the Godzilla franchise (http://en.wikipedia.org/wiki/Godzilla_(1998_film)).
The headline is directly inspiring people to imagine what kind of size they will see the actual giant-monster lizard, frightening everybody on movie and in the theater.
Yup, something big is very important.
We usually perceive big is better only by hearing about that, not seeing the fact first.
Then, when you have a campaign about a product with big benefit because its big size for your target audience, I think you must say it big...although you have a tiny budget.
You can go first with sticker. Use this copy.
(Mmh...dare you to stick it on public toilet, especially men's room?)
Think BIG. Not bug
