The objective is a bit different in the case of “beltbag”
It is to remind us of a practice of yesteryear.
And be a reminder that average people can solve their own everyday problems in an adhoc manner.
The concept itself is not really a product but the promotion of a behavior.
We all have “beltbag”. There is no need to purchase of course, just remember it is a possibility if ever in a pinch.
As well, our entry’s tone is just as important as the concept itself.
There is something attractive about our character’s nonchalance. Like he couldn’t be bothered to bring a bag so his belt will just have to do. And of course he couldn’t be troubled to study for that history test, so the inside of the belt is treated so he can jot down the answer he got from his buddy.
It is that casual indifference we all sought when we were 17. This nuance can be difficult to impart through a sterile hypershot rendering.
