If you are not particularly experienced in rolling cigarettes with your hands only, you are in need of a cigarette rolling machine. It's simple to use: put in some tobacco, add a paper of your choice and just spin the machine. The result is a cigarette of a quality near to that of boxed ones.
Cigarette rolling machines are available in two special sizes: For long papers and for standard size papers. The first ones are about 110mm long, the latter only about 70mm. The choice for one of the machines depends on the size of the cigarette you want to roll. Machines with 110mm are also apt for blunts, but it takes some practice to roll a tabacco leaf.
The standard rolling machines fabricate the familiar cigarettes. If you want to have conical tubes you would need a special version.
