You gotta break em in! Also make sure you put the koozie on the can before you open it. It helps.
They did fit on Coors lights very nicely though. A lot of coozies are on the looser side for those beers.
Yeah that would be pretty cool to do limited runs of things. It just costs more per unit to do small runs instead of bulk orders.
I'll have to hit up my buddy Nick to design some sweet shirts for us.
