A cone is a pre-rolled joint sleeve. Available in bleached or unbleached cigarette paper, the fine casings already have rolled-up filters or tips in their mouthpiece. Especially good cones are suitable for smokers who are not good at building cigarettes, be it for lack of talent or health reasons. Cones are, as the name suggests, conical in shape and narrow towards the filter. They are available in different sizes, from the length of a normal cigarette over King Size format to Giga Cones with up to 28cm in length.
