I work in stone construction (natural and manufactured). I build mods as a hobby. I built my VW bottomfeeder box for work duty. It's an aluminum project box with dna 12. I have a SS ERA clone on top. It's the size of a pack of stinkies with an ERA on top. Fits in my pocket just fine. This is the reason tube mods are negative bueno in my book. If I can't stick it in my pocket comfortably... NO
