Recommended Tubes: These machines will work with most standard brands of 8mm cigarette tubes with a filling chamber between 66mm and 68mm (Total Length - Filter Length.) Most brands are universal but Imperial tobacco again are trying to manipulate the tubing market so you they entice you to buy their tubing machine at a discounted price then force you to buy their tubes at an inflated price. So the "Rizla Concept" and "make your own" tubes are too small for this machine and will likely tear when using this machine. You can get away with making a cigarette with the "Rizla Concept" and "make your own" tubes if you are careful.
