 American-sized (350 ml) cans are almost non-existent, although Dydo produces one of that size called "American Coffee".Barrel-shaped cans are also fairly popular, while an aspect of the Roots' marketing campaign is the company's unique "waist-shaped" can.A new kind of cone top type can with a twist-off cap has appeared in recent years, and many companies offer at least one of their coffee types in this kind of container.
